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.
The AD7609 operates from a single 5 V supply and can accommodate ±20 V and ±10 V true bipolar differential input signals while sampling at throughput rates up to 200 kSPS for all channels. The input clamp protection circuitry can tolerate voltages up to ±16.5 V on each analog input pin. The AD7609 has 1 MΩ analog input impedance regardless of sampling frequency. The single supply operation, on-chip filtering, and high input impedance eliminate the need for driver op amps and external bipolar supplies. The AD7609 antialiasing filter has a −3 dB cutoff frequency of 32 kHz and provides 40 dB antialias rejection when sampling at 200 kSPS. The flexible digital filter is pin driven, yields improvements in SNR, and reduces the −3 dB bandwidth.
Applications
- Power line monitoring and protection systems
- Multiphase motor control
