DAC7742Y/250

Digital To Analog Converters Overview

The DAC7742Y/250 is a 16-bit single-channel digital-to-analog converter featuring an internal +10V reference and parallel interface. It provides 16 bits of monotonic performance over the specified operating temperature range. The output swing can be configured in ±10V, ±5V, or +10V ranges via pin strapping. Key electrical parameters include a maximum settling time of 5 µs to ±0.003% FSR for a 20V full-scale change, typical power consumption of 100mW, and INL/DNL errors of ±6 LSB and ±4 LSB respectively. It operates from analog supplies of ±11.4V to ±15.75V and a digital supply of 5V.

Digital To Analog Converters Feature Summary
