Design DAC161P997
SNAS515G – JULY 2011 – REVISED DECEMBER 2014 DAC161P997 Single-Wire 16-bit DAC for 4-to 20-mA Loops
1 Features 3 Description The DAC161P997 is a 16-bit ∑Δ 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/В°C) and
excellent long-term output current drift (90 ppmFS)
while consuming less than 190 ВµA. 1 16-Bit Linearity
Single-Wire Interface (SWIF), with Handshake
Digital Data Transmission (No Loss of Fidelity)
Pin Programmable Power-Up Condition
Self Adjusting to Input Data Rate
Loop Error Detection and Rreporting
Programmable Output Current Error Level
No External Precision Components
Simple Interface to HART Modulator …
