The LTC1591/LTC1597 are pin compatible, parallel input 14-bit and 16-bit multiplying current output DACs that operate from a single 5V supply. INL and DNL are accurate to 1LSB over the industrial temperature range in both 2- and 4-quadrant multiplying modes. True 16-bit 4-quadrant multiplication is achieved with on-chip 4-quadrant multiplication resistors.These DACs include an internal deglitcher circuit that reduces the glitch impulse to less than 2nV-s (typ). The asynchronousCLRpin resets the LTC1591/LTC1597 to zero scale and LTC1591-1/LTC1597-1 to mid-scale.The LTC1591/LTC1597 are available in 28-pin SSOP and PDIP packages and are specified over the industrial temperature range.For serial interface 16-bit current output DACs refer to the LTC1595/LTC1596 data sheet.ApplicationsProcess Control and Industrial AutomationDirect Digital Waveform GenerationSoftware-Controlled Gain AdjustmentAutomatic Test Equipment

The LTC1594L/LTC1598L are 3V micropower, 12-bit sampling A/D converters that feature 4- and 8-channel multiplexers, respectively. They typically draw only 160µA of supply current when converting and automatically power down to a typical supply current of 1nA between conversions. The LTC1594L is available in a 16-pin SO package and the LTC1598L is packaged in a 24-pin SSOP. Both operate on a 3V supply. The 12-bit, switched capacitor, successive approximation ADCs include a sample-and-hold.On-chip serial ports allow efficient data transfer to a wide range of microprocessors and microcontrollers over three or four wires. This, coupled with micropower consumption, makes remote location possible and facilitates transmitting data through isolation barriers.The circuit can be used in ratiometric applications or with an external reference. The high impedance analog inputs and the ability to operate with reduced spans (to 1.5V full scale) allow direct connection to sensors and transducers in many applications, eliminating the need for gain stages.ApplicationsPen Screen DigitizingBattery-Operated SystemsRemote Data AcquisitionIsolated Data AcquisitionBattery MonitoringTemperature Measurement
