linear technology corp (LLTC) Key Developments

Linear Technology Corporation Introduces LTC2645 Digital-To-Analog Converter

Linear Technology Corporation has introduced the LTC2645, a quad-channel 12-bit/10-bit/8-bit PWM-to-voltage output digital-to-analog converter, or DAC, with 10ppm/°C reference. These parts convert PWM input signals to 12-bit accurate, stable, buffered voltage outputs in less than 8µs, eliminating the ripple and delay typically associated with analog filters. The LTC2645 provides a simple bolt-on solution to accurately set and adjust four voltages without a single line of code required. Offered in a small 16-lead MSOP package, the LTC2645 is ideal for biasing, calibration, level setting, power supply adjustment, and to enable opto-isolated communications in applications such as industrial automation, 4-20mA process control, instrumentation, test equipment and optical modules. A dual version, the LTC2644, is available in a 12-lead MSOP package. The LTC2645 measures the period and pulse width of the PWM input signals and updates the DACs after each PWM input rising edge, accepting PWM input frequencies from 30Hz up to 100kHz. An IDLSEL pin provides flexibility to set the outputs to idle at zero- or full-scale, power-down with high-impedance output, or hold the previous state indefinitely in response to an idle PWM input. This convenient mode has the advantage over analog filter implementations, which require the PWM to run continuously. Each rail-to-rail DAC output is capable of sourcing or sinking 5mA (3V) or 10mA (5V), and offers a full-scale output of 2.5V using the internal 10ppm/°C reference or a full-scale output equal to the external reference. The LTC2645 operates from a single 2.7V to 5.5V supply, and supports PWM input voltages from 1.71V to 5.5V.

Linear Technology Corporation Unveils New LTC5599 Low Power I/Q Modulator

Linear Technology Corporation has unveiled new LTC5599, a low power I/Q modulator. A new LTC5599 low power I/Q modulator enables battery-powered transmitters operating in the 30MHz to 1.3GHz bands, breaking new ground in power consumption, sideband suppression, carrier leakage and dynamic range performance. The LTC5599 modulator, powered from a single 2.7V to 3.6V supply, draws only 28mA current, less than 60% that of alternative solutions -with no performance sacrifice. The LTC5599 delivers outstanding native -52.6dBc sideband suppression and -51.5dBm carrier leakage without calibration. With on-chip calibration resources, performance can be further improved to -60dBc and -65dBm, respectively. Moreover the device output achieves an excellent noise floor of -156dBm /Hz with an OIP3 of 20.8dBm, delivering superior transmitter performance. The LTC5599 combines low power consumption and robust performance to suit a wide range of demanding battery-powered radios and wireless communications applications that are exposed to strong radio interference. These include wireless professional microphones, frequency hopping narrowband and broadband portable field radios, public safety radios, train communications, as well as broadband VHF/UHF white space modems, software- defined radios, portable RF test equipment, picocell base stations, low-power microwave backhaul, small wireless repeaters and satellite modems. The device's gain can be set via the on-chip serial port. A coarse gain control provides 1dB/step, along with adjustable fine gain control of 0.1dB. Total gain ranges from -19dB to 0dB. Varying the modulator gain enables device supply current from 8mA to 35mA, allowing the device to be set to lower power consumption with s lightly reduced gain and performance, as needed for specific applications . Once set, the gain can be automatically temperature compensated by activating the on-chip temperature correction feature. The LTC5599 supports narrowband and wideband radio applications. Its I and Q inputs are each capable of -1dB modulation bandwidth of up to 37MHz, supporting a total of 74MHz RF bandwidth at 900MHz frequency. The LTC5599 is available in a 4m m x 4m m QFN package, providing a com pact footprint. The product is specified for case operating temperature from -40°C to 105°C, supporting reliable operation in extended temperature environments. The device can be conveniently shut down with an enable control pin. When disabled, the device conserves power by drawing a typical of 0.7µA standby current.

Linear Technology Corporation Introduces LTC4121 Charger

Linear Technology Corporation introduced the LTC4121, a constant- current/constant-voltage 400mA charger for Lithium -Ion, LiFePO4 and lead-acid batteries. The LTC4121's high efficiency, synchronous step-down topology accepts a wide 4.4V to 40V input. A programmable 3.5V to 18V battery charge voltage range with tight +/-1% accuracy makes the LTC4121 suitable for a variety of battery chemistries. The fixed output float voltage version, LTC4121-4.2, is suitable for 1S lithium -ion battery packs. Asynchronous architecture enables charging efficiency up to 94% as well as low dropout start-up and operation. Typical applications include handheld instruments, solar-powered devices, as well as industrial and military sensors and devices. To accommodate high impedance input sources such as solar panels, the LTC4121 can regulate its input voltage to a programmable percentage of the input open circuit voltage. If the input voltage falls below the user-defined percentage of the open circuit voltage, charge current will be automatically reduced. This maximum power point tracking (MPPT) technique enables maximum power operation with a variety of high impedance input sources, even in non-ideal operating environments. The LTC4121 features programmable charge current from 50mA to 400mA and low voltage battery preconditioning. A recharge function starts a new charging cycle if the battery voltage drops 2.2% below the program med charge voltage. Safety features include a two-hour termination timer as well as NTC temperature qualified charging. Two open-drain outputs provide charge and fault status information. The LTC4121 is housed in a low profile (0.75m m) 16-pin 3mm x 3mm QFN package with exposed pad for excellent thermal performance. The device is guaranteed for operation from -40°C to 125°C in both E and I grades.
