The AD4682 and the AD4683 are a 16-bit, pin-compatible family of dual, simultaneous sampling, high speed, low power, successive approximation register (SAR), analog-to-digital converters (ADCs) that operate from a 3.0 V to 3.6 V power supply and feature throughput rates up to 1 MSPS for the AD4682 and 500 kSPS for the AD4683. The analog input type is pseudo differential and is sampled and converted on the falling edge of CS.
Integrated on-chip oversampling blocks improve dynamic range and reduce noise at lower bandwidths. A buffered internal 2.5 V reference is included. Alternatively, an external reference up to 3.3 V can be used.
The conversion process and data acquisition use standard control inputs that allow simple interfacing to microprocessors or digital signal processors (DSPs). The devices are compatible with 1.8 V, 2.5 V, and 3.3 V interfaces, using a separate logic supply.
Applications
- Motor control position feedback
- Motor control current sense
- Sonar
- Power quality
- Data acquisition systems
- Erbium doped fiber amplifier (EDFA) applications
- Inphase (I) and quadrature (Q) demodulation
