Overview
The AD7922AUJ-REEL7 is a dual-channel, 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single 2.35 V to 5.25 V supply and supports throughput rates up to 1 MSPS. The device features an on-chip track-and-hold amplifier with a wide input bandwidth capable of handling frequencies exceeding 6 MHz. It utilizes a flexible serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. Power consumption is low, typically 4.8 mW at 1 MSPS with 3 V supplies. The component is housed in an 8-lead TSOT package.
Feature Summary
- Dual-channel architecture with high-speed 1 MSPS throughput capability
- Low power operation with dedicated standby mode for current reduction
- Flexible serial interface supporting multiple standard protocols
- Integrated track-and-hold amplifier for wide input bandwidth
Applications
- Battery-powered systems such as personal digital assistants
- Medical instruments requiring precise signal acquisition
- Mobile communications equipment
- Instrumentation and control systems
- Data acquisition systems
Procurement Notes
Verify the specific ordering suffix AUJ against official documentation to confirm the 8-lead TSOT package configuration. Ensure compatibility with the required voltage range of 2.35 V to 5.25 V for your application design. Confirm that the A Grade temperature range of −40°C to +85°C meets your operational environment requirements before finalizing procurement.
Selection Notes
Select this component when a dual-channel 12-bit resolution is required alongside high-speed sampling capabilities. It is suitable for designs needing low power consumption without sacrificing throughput. Consider the external reference requirement derived from VDD when designing the power supply network. Evaluate the serial interface timing constraints to ensure compatibility with the host microprocessor or DSP clock speeds.
Part Context
This part belongs to the AD7912/AD7922 family of high-speed, low-power ADCs. The AD7922 variant specifically provides 12-bit resolution compared to the 10-bit AD7912. Both share identical pinouts and functional characteristics, differing primarily in resolution and associated linearity specifications. The family is designed for space-constrained applications utilizing small surface-mount packages.
Replacement Considerations
The AD7912 serves as a lower-resolution alternative within the same package and family. Verify if 10-bit resolution suffices for your application to potentially reduce costs. No other direct substitutes are confirmed in the provided documentation.
