Overview
The AD7920BKSZ-REEL is a 12-bit, 200 kSPS analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It utilizes successive approximation register (SAR) architecture and operates from a single 2.7 V to 5.5 V power supply. The device features an on-chip high-speed track-and-hold amplifier and a low-power SAR ADC core. It communicates via a flexible serial interface compatible with standard SPI, QSPI, MICROWIRE, and DSP standards. The component is housed in a compact SC-70-6 surface-mount package, designed for space-constrained applications requiring precision data acquisition.
Feature Summary
- 12-bit resolution with 200 kSPS sampling rate
- Single-supply operation from 2.7 V to 5.5 V
- On-chip track-and-hold amplifier
- Flexible serial interface compatible with SPI/QSPI/MICROWIRE
Applications
- Portable instrumentation
- Battery-powered systems
- Data acquisition systems
- Industrial process control
Procurement Notes
Verify the specific suffix 'B' against the manufacturer's current datasheet to confirm voltage range and accuracy grades. Confirm the 'REEL' packaging designation matches the required reel size for automated assembly lines. Check RoHS compliance status as per the latest manufacturing documentation.
Selection Notes
Select this component when a balance of moderate speed (200 kSPS) and high resolution (12-bit) is required in a minimal footprint. Ensure the input signal range aligns with the reference voltage capabilities. Verify that the serial interface timing meets the system clock requirements for the chosen communication mode.
Part Context
This part belongs to the AD7920 family of low-power, 12-bit ADCs. The 'KSZ' indicates the SC-70-6 package type, while 'REEL' specifies tape-and-reel packaging for high-volume surface-mount processing. It serves as a drop-in replacement for older generations of SAR ADCs in compact designs.
Replacement Considerations
Direct substitutes include other parts within the AD7920 family with different suffixes for package or temperature variations. Cross-reference with AD7920 variants offering different sampling rates or pinouts if form factor changes are permissible.
