DAC7821 Description

Short technical summary and product information.

The Texas Instruments DAC7821 is a CMOS 12-bit current output digital-to-analog converter (DAC). This device is designed for applications requiring precise analog output, operating from a single 2.5V to 5.5V power supply, making it suitable for battery-powered devices.

 

Key electrical specifications include a 12-bit resolution, a fast parallel interface with a 17ns write cycle, and an update rate of 20.4MSPS. It offers a multiplying bandwidth of 10MHz and a ±10V reference input. The DAC7821 boasts a low glitch energy of 5nV-s and integral non-linearity (INL) of ±1 LSB. Its settling time is a rapid 0.2 µs.

 

This DAC features a 4-quadrant multiplication architecture and an extended operating temperature range of -40°C to +125°C. It includes power-on reset with brownout detection and a readback function, allowing users to read the DAC register contents via the DB pins. The device is available in a 20-lead TSSOP package.

 

Applications for the DAC7821 include portable battery-powered instruments, waveform generators, analog processing, programmable amplifiers and attenuators, digitally-controlled calibration, programmable filters and oscillators, and composite video systems.
