概述
Description
The AD7865BSZ-1 is a 12-bit, 4-channel, simultaneous sampling ADC from Analog Devices. It features pseudo-differential inputs, a fast conversion rate (up to 1.5 MSPS total throughput), and a ±10V input range.
Key features:
- 4 synchronous sampling channels for accurate multi-signal capture.
- On-chip track-and-hold for signal integrity.
- SPI-compatible serial interface for easy microcontroller integration.
- Low power consumption (~60 mW at max speed).
Applications include motor control, power monitoring, and data acquisition systems where simultaneous multi-channel sampling is critical. The device operates on a single +5V supply and includes a reference voltage (2.5V).
Package: 44-lead MQFP.
For detailed specs, refer to the datasheet.
