Übersicht
Description
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.
Equivalent
- AD7865BSZ-2 (higher throughput variant)
- AD7865ASZ-1 (lower power version)
- LTC1865 (similar specs, from Linear Tech)
- MAX186 (12-bit, 8-channel, from Maxim)
- ADS7865 (from Texas Instruments)
These alternatives offer comparable resolution, channel count, and interface options. Always verify pin compatibility and specifications for your application.
