Overview
The AD7983BCPZ-R2 is a 16-bit successive approximation analog-to-digital converter (ADC) from the PulSAR family, manufactured by Analog Devices Inc. It operates on a single 2.5 V supply with a logic interface compatible with 1.8 V to 5 V levels. The device achieves a throughput of 1.33 MSPS with a total power dissipation of 10.5 mW at maximum speed and 80 μW at 10 kSPS. It features a pseudo-differential input range of 0 V to VREF (2.9 V to 5.1 V), an SNR of 92 dB, and an INL of ±1.0 LSB maximum. Packaged in a 10-lead LFCSP, it supports SPI/QSPI/MICROWIRE/DSP interfaces.
Feature Summary
- Zero-latency architecture providing immediate data availability without pipeline delay
- Low power consumption scaling linearly with throughput for battery-operated applications
- Versatile serial interface supporting daisy-chaining multiple ADCs on a single bus
Applications
- Automated test equipment
- Data acquisition systems
- Medical instruments
- Machine automation
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Ensure the external reference voltage falls within the 2.9 V to 5.1 V range for optimal performance. Confirm that the host system logic voltage matches the VIO supply requirements for proper digital interface compatibility.
Selection Notes
Select this component when a high-resolution 16-bit conversion is required alongside low power consumption. The pseudo-differential input structure helps reject common-mode noise. Consider the available packages, MSOP or LFCSP, based on board space constraints. Ensure the application can provide a stable external reference voltage within the specified operating temperature range.
Part Context
The AD7983 belongs to the PulSAR ADC series, designed for precision data acquisition tasks. It shares architectural similarities with other 16-bit SAR converters but distinguishes itself through its specific combination of speed and power efficiency. The device is pin-compatible with certain 18-bit variants, facilitating design upgrades.
Replacement Considerations
The AD7982 is a pin-for-pin compatible 18-bit version offering higher resolution. For lower speed requirements, the AD7680 series provides similar functionality with reduced throughput.
