概述

Description

DAC9881SRGET is a digital-to-analog converter (DAC) from TI. It converts a digital word into a precise analog voltage using a serial interface (typically SPI-like: DIN, SCLK, CS, LDAC). Key points:
- Function: 1 (or more) channel DAC that produces an analog output proportional to the input code, with reference input shaping the output range.
- Interface: serial input for loading codes; may include a LDAC or update feature to transfer the code to the output.
- Resources: external Vref/reference pin, power-supply pins, ground.
- Package suffix: GET usually denotes RoHS-compliant packaging; exact package type is in the datasheet.
- Applications: precision control, calibration, waveform generation, test and measurement.
For exact specifics (bit resolution, voltage range, settling time, power-down modes, current drive, pinout), please consult the DAC9881SRGET datasheet from TI. If you have a particular requirement (voltage range, reference method, or interface), I can tailor guidance accordingly.

Package

The DAC9881SRGET comes in a 16‑pin Small Outline IC package (SOIC), RoHS-compliant (Pb-free) and suitable for extended temperature operation.

Pinout

- Pin count: 8 pins (SOIC-8 package code SRGET)
- Function: Single-channel, serial-input (SPI-compatible) voltage-output digital-to-analog converter. Converts a digital word to an analog voltage relative to a reference.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: A global semiconductor company that designs and manufactures analog and embedded processing integrated circuits, microcontrollers, and other electronic components.

Application

General-purpose digital-to-analog converter for generating precise analog voltages from digital data. Common applications include:
- Instrumentation and data acquisition systems
- Industrial process and factory automation control
- Motor and servo control
- Programmable power supplies and voltage/current sources
- Test and measurement equipment (ATE)
- Medical devices needing precise analog signals
- Calibration, sensor signal conditioning, and offset/gain adjustment
- Signal generation and waveform synthesis

Equivalent

Do you need exact pin- and footprint-compatible substitutes, or any 12-bit SPI DAC with similar performance? Also share required package, supply voltage, temperature range, and whether you need a multiplying DAC. Then I can give precise cross‑references.
