AD7886 is a 12-bit ADC with a sample-and-hold amplifier offering high speed performance combined with low power dissipation
The AD7886 is a 12-bit analog-to-digital converter (ADC) with a sample-and-hold amplifier, designed for high-speed performance combined with low power dissipation. It utilizes a triple-pass flash architecture with 15 comparators to achieve 12-bit accuracy within a 1 µs conversion time. The device operates from ±5 V power supplies and includes an on-chip clock oscillator to eliminate the need for external clocks.
| Throughput Rate | 750 kHz/1 MHz |
|---|---|
| Conversion Time | 1 µs/750 ns |
| Operating Temperature (J, K Versions) | 0 °C to +70°C |
The device offers three pin-strappable input ranges: 0 V to 5 V, 0 V to 10 V, or ±5 V.
No, it features an on-chip clock oscillator that provides appropriate timing for each conversion stage.
It uses standard microprocessor signals CS and RD for data access and has a data access time of less than 57 ns.
