- Part Number:
- AD7866BRU
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3013643-AD7866BRU
- Description:
- IC ADC 12BIT 2CH DUAL 20-TSSOP
- ECAD Model:
-
- Datasheet:
- AD7866BRU
Description
The AD7866 is a dual 12-bit, 2-channel successive approximation ADC with a serial interface. It operates from a single 2.7 V to 5.25 V power supply and features throughput rates up to 1 MSPS. Each ADC has a 2-channel input multiplexer, and the conversion results of both channels are available simultaneously on separate data lines. The AD7866 has an on-chip 2.5 V reference that can be overdriven if an external reference is preferred. Each on-board ADC can also be supplied with a separate individual external reference.
Features
Dual 12-bit, 2-channel ADC
Throughput rate: 1 MSPS
Low power consumption: 11.4 mW max at 1 MSPS with 3 V supplies
Wide input bandwidth: 70 dB SNR at 300 kHz input frequency
On-board reference: 2.5 V
Flexible power/throughput rate management
Simultaneous conversion/read
No pipeline delays
High speed serial interface: SPI/QSPI/MICROWIRE/DSP compatible
Shutdown mode: 1 μA max
Applications
Data acquisition systems
Process control
Medical instrumentation
Industrial automation
Test and measurement
