DAC7641Y/2K

Digital To Analog Converters Overview

The DAC7641Y/2K is a single-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes a resistor-string architecture and features a parallel interface for data input. The device operates with an analog supply voltage range of 4.75 V to 5.25 V and a digital supply voltage range of 2.7 V to 5.5 V. Key electrical specifications include a settling time of 10 µs, a differential nonlinearity (DNL) of ±1 LSB, and an integral nonlinearity (INL) of ±64 LSB. The gain error is specified at 0.8% FSR. It is housed in a TQFP-32 package and supports an operating temperature range from -40°C to +85°C.
