Overview

Description

The AD7680BRM is Analog Devices’ high‑resolution ADC (16‑bit) with a serial SPI‑style interface. It uses a SAR architecture with an integrated sample/hold and supports unipolar or bipolar input ranges, making it suitable for instrumentation and data‑acquisition tasks. It can operate from a single supply and offers options for internal or external references, with a 16‑bit output word via the serial interface. The BRM suffix indicates a compact package variant. Typical applications include test equipment, process monitoring, and portable instrumentation requiring precise, mid‑speed conversions. For exact specs—full‑scale range, input bandwidth, conversion speed, power, and reference options—refer to the official AD7680 datasheet.

Features

AD7680BRM features (typical):
- 12-bit SAR ADC
- Up to 1 MSPS conversion rate
- SPI-compatible serial interface (SCLK, DIN, DOUT, CS)
- Single-supply operation: 2.7 V to 5.25 V
- Input range: 0 to VREF (unipolar)
- Internal reference option with external reference input
- On-chip track-and-hold
- Low-power modes and shutdown
- Monotonic, with no missing codes
- Industrial temperature range: −40°C to +85°C
- Package: BRM (compact 28-lead/BRM package)
Note: verify exact package and electrical specs in the latest ADI datasheet.

Pinout

- Pin count: 28 pins (LQFP/SOIC package typical for AD7680BRM).
- Function: 12-bit, 8-channel multiplexed analog-to-digital converter (ADC) with an SPI-compatible serial interface (eight analog inputs multiplexed to a single ADC, with serial data output).

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI)
- Company type: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits.
