LTC2672 Overview
Key Specifications
Pins: 32
Description
Per channel programmable output current ranges: 300 mA, 200 mA, 100 mA, 50 mA, 25 mA, 12.5 mA, 6.25 mA, and 3.125 mA - Flexible 2.1 V to VCC output supply voltages - Flexible single- or dual-supply operation - 0.6 V maximum dropout voltage guaranteed - Separate voltage supply per output channel - Internal switches to optional negative supply - Full 12-bit and 16-bit resolution at all ranges - Guaranteed operation -40°C to 125°C (H-grade) - Precision internal reference or external reference - Internal VREF temperature coefficient of 10 ppm/°C maximum (LFCSP) or 2.4 ppm/°C nominal (WLCSP) - Analog multiplexer monitors voltages and currents - A/B toggle via SPI or dedicated pin - 1.71 V to VCC digital input and output supply voltage - 32-lead lead frame chip scale package (LFCSP) - 36-ball wafer level chip scale package (WLCSP) The LTC2672 is a family of five-channel, 12-/16-bit current source, digital-to-analog converters (DACs) that provide five high compliance, current source outputs with guaranteed 0.6 V dropout at 200 mA. There are eight current ranges that are programmable per channel with full-scale outputs of up to 300 mA.
