AD7609 datasheet

Description :

The AD7609 is an 18-bit, 8-channel, true differential, simultaneous sampling analog-to-digital data acquisition system (DAS). The part contains analog input clamp protection, a second-order antialiasing filter, a track-and-hold amplifier, an 18-bit charge redistribution successive approximation analog-to-digital converter (ADC), a flexible digital filter, a 2.5 V reference and reference buffer, and high speed serial and parallel interfaces.

1. 8 simultaneously sampled inputs
2. True differential inputs
3. True bipolar analog input ranges: ±10 V, ±5 V
4. Single 5 V analog supply and 2.3 V to 5.25 V VDRIVE
5. Fully integrated data acquisition solution
6 Analog input clamp protection
7. Input buffer with 1 MΩ analog input impedance
8. Second-order antialiasing analog filter
9. On-chip accurate reference and reference buffer
10. 18-bit ADC with 200 kSPS on all channels
11. Oversampling capability with digital filter
12. Flexible parallel/serial interface
13. SPI/QSPI™/MICROWIRE™/DSP compatible
14. Performance
15. 7 kV ESD rating on analog input channels
16. 98 dB SNR, −107 dB THD
17. Dynamic range: up to 105 dB typical
18. Low power: 100 mW
19. Standby mode: 25 mW
