3 Description

The DAC161P997 is a 16-bit ΣΔ digital-to-analog

converter (DAC) for transmitting an analog output current over an industry standard 4-20 mA current

loop. It offers 16-bit accuracy with a low output

current temperature coefficient (29 ppm/°C) and

excellent long-term output current drift (90 ppmFS) while consuming less than 190 μA.

The data link to the DAC161P997 is a Single Wire Interface (SWIF) which allows sensor data to be

transferred in digital format over an isolation

boundary using a single isolation component. The

DAC161P997’s digital input is compatible with

standard isolation transformers and opto-couplers. Error detection and handshaking features within the

SWIF protocol ensure error free communication

across the isolation boundary. For applications where

isolation is not required, the DAC161P997 interfaces

directly to a microcontroller.

The loop drive of the DAC161P997 interfaces to a

HART (Highway Addressable Remote Transducer) modulator, allowing injection of FSK modulated digital

data into the 4-20 mA current loop. This combination

of specifications and features makes the

DAC161P997 ideal for 2- and 4-wire industrial

transmitters.

The DAC161P997 is available in a 16–lead WQFN

package and is specified over the extended industrial temperature range of -40°C to 105°C.
