SGM5348-12XTS16G/TR

The SGM5348-12XTS16G/TR from SG Micro Corp is an 8-channel, 12-bit digital-to-analog converter (DAC) featuring integrated output operational amplifiers with high current drive capability. Data is communicated via an SPI interface, supporting daisy-chain connections for simultaneous updates across multiple devices. This DAC offers independent power-down functionality for each channel and incorporates a power-on reset circuit that defaults outputs to 0V until a valid write occurs.

Key electrical specifications include a wide power supply voltage range of 2.8V to 5.5V and independent reference voltage inputs ranging from 0.5V to VCC. The device boasts low power consumption, rated at 0.5mW per channel, with significantly reduced current draw in power-down mode (less than 1.5μW at 3V). It also features a typical gain error of 0.1% across all channels and supports serial data input up to 40MHz with TTL-compatible logic levels.

Designed for extended industrial applications, the SGM5348-12XTS16G/TR operates reliably within a temperature range of -40℃ to +125℃. It is available in TSSOP-16 and TQFN-3x3-16L packages, both suitable for surface mount assembly. Applications include battery-powered equipment, selectable voltage and current sources, ADC voltage references, sensor power supplies, and audio signal volume control.
