概述

Description

AD7680BRM is Analog Devices’ SAR ADC with a SPI-compatible serial interface, used for precision data acquisition. It typically provides around 12-bit resolution at up to about 1 MSPS, with low power and single-supply operation (roughly 3–5.5 V). It supports single-ended or differential inputs tied to an external reference (external ref preferred; some variants offer internal options). The BRM suffix denotes the specific package/grade (temperature range and packaging) for this part. Key pins include DIN, DOUT, SCLK, CS, VREF, VIN+, VIN−, VDD, and GND. Applications include instrumentation, process control, motor/sensor interfaces, and embedded data-acquisition systems. For exact resolution, throughput, power, reference options, and packaging, consult the AD7680BRM datasheet.

Features

AD7680BRM is a 12‑bit, high‑performance SAR ADC. Key features include:
- 12‑bit resolution with SAR architecture
- Up to about 1 MSPS conversion rate
- Single‑supply operation from 2.7 V to 5.25 V
- On‑chip sample‑and‑hold
- SPI‑compatible serial interface (DIN, DOUT, SCLK, CS)
- Input range: 0 to Vref (unipolar); external reference input plus optional internal reference
- Internal reference option (e.g., 2.5 V) plus external reference capability
- Low power modes including power‑down
- Wide operating temperature range (industrial/extended as provided)
- 28‑lead package (BRM variant), suitable for compact board designs
Applications include data acquisition, instrumentation, and sensor interfacing where a small, low‑power, high‑resolution ADC with a serial interface is advantageous. For exact electrical specs and package details, refer to the latest Analog Devices datasheet for AD7680BRM.

Package

The AD7680BRM is in a 28‑lead plastic TSSOP (small‑outline) package.

Pinout

- Pin count: 8 pins (MSOP-8 package, BRM suffix)
- Function: 12-bit, 5 MSPS ADC with SPI‑like serial interface. Analog input: VIN; reference: VREF; power: AVDD and GND; digital interface pins: CS, SCLK, DIN, DOUT.
