概述

Description

AD574AJPZ is Analog Devices’ 12‑bit multiplying digital‑to‑analog converter (MDAC). It multiplies a 12‑bit digital word by an external reference or analog input to produce an analog output proportional to that product, enabling true bipolar output for programmable gain, waveform generation, and calibration. The A revision generally offers improved accuracy and temperature stability over the original. The device is typically a current‑output DAC that requires an external I→V conversion (or can be used with an external op‑amp to obtain a voltage output). The suffix J PZ denotes the package/temperature grade; check the datasheet for exact package and lead finish. Typical applications include precision control, instrumentation, DAC‑based multiplying, and programmable gain/offset in analog systems. For exact electrical specs, pinout, timing, and packaging, refer to the AD574A datasheet.

Features

AD574AJPZ features (concise):
- 12-bit multiplying DAC (MDAC) with current-output
- SPI-compatible serial data input
- External reference input to set full-scale
- External op-amp required to convert Iout to voltage (voltage output option via Iout conversion)
- Monotonic, low-glitch performance
- Wide operating range: suitable for single/dual supplies and industrial temp ranges
- Package: 28-pin J-lead (AJPZ suffix)
Note: For exact electrical specs (INL/DNL, settling time, supply ranges, and temperature limits), please refer to the official datasheet.

Package

AD574AJPZ comes in a 16‑pin plastic DIP (PDIP) package.

Pinout

- Pin count: 8 pins (in its AD574AJPZ package).
- Function: Digital-to-analog converter (DAC) – converts a digital input code to an analogue output (voltage or current, as configured with external circuitry).

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI)
- What kind of company: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits and sensors; a global leader in data conversion, signal processing, and sensor technologies.

Application

AD574AJPZ is a 12-bit multiplying DAC. Key application areas include:
- Programmable gain/attenuation and precision signal conditioning for control loops
- Programmable waveform generation and modulation in generators and test equipment
- Analog computing and signal processing (digital-controlled multiplication and scaling)
- Instrumentation, data acquisition, and sensor calibration/compensation
- Industrial control and servo/motor-control applications requiring scaled references to drive amplifiers or voltage/current outputs

Equivalent

AD574AJPZ is a 12‑bit multiplying DAC (MDAC) with current output. There isn’t an exact drop‑in equivalent across manufacturers. Closest cross‑references are other 12‑bit MDACs, e.g. Analog Devices AD575x/AD57x families, Texas Instruments DAC761x (and similar) series, and Maxim MAX517x/MAX51x families, depending on interface (SPI/I2C/parallel) and output (current vs voltage). For a precise cross, use the vendor cross-reference tool or distributor catalog with your required package and interface.
