The DAC161S997RGHR from Texas Instruments is a highly integrated, 16-bit Delta-Sigma digital-to-analog converter (DAC) specifically designed for transmitting analog output current over an industry-standard 4-20 mA current loop. This device utilizes a simple 4-wire SPI interface for data transfer and configuration.
Key electrical specifications include a 16-bit resolution, an integral non-linearity (INL) of ±9 LSB, and an external reference type. It operates with a supply voltage range of 2.7V to 3.6V and consumes very low power, typically 0.33mW with a supply current of only 100 µA. The operating temperature range is extended industrial, from -40°C to 105°C.
Designed for industrial transmitters, the DAC161S997RGHR includes features like loop-error detection and reporting, programmable output-current error levels, and simple HART modulator interfacing. Its highly integrated feature set and small footprint make it suitable for compact, loop-powered applications. The device is available in a 16-pin WQFN package with surface mount mounting type.
This DAC is ideal for 2- and 4-wire industrial transmitters where low power consumption and precise current loop control are essential. The internal voltage reference and oscillator further reduce component count and power requirements.
