Description
The AD7927BRUZ is a 12-bit, 8-channel successive approximation analog-to-digital converter (ADC) from Analog Devices. It operates at a 1 MSPS sampling rate and features a serial interface (SPI-compatible) for communication with microcontrollers or DSPs.
Key features:
- 8 single-ended or 4 pseudo-differential inputs
- Low power consumption (3.5 mW at 1 MSPS, 15 µW in shutdown)
- 2.7V to 5.25V supply range
- On-chip track-and-hold and reference buffer
Applications include data acquisition, industrial control, and medical instrumentation. The 20-lead TSSOP package makes it suitable for space-constrained designs.
Its high throughput, low power, and flexible input configuration make it ideal for multi-channel systems requiring precise analog-to-digital conversion.
