Overview
The AD7896BNZ is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.7 V to 5.5 V, with the VDD pin serving as the internal reference. The device features an on-chip track-and-hold amplifier and achieves a throughput rate of up to 100 kHz with an 8 µs conversion time in high-speed mode. It utilizes a 2-wire serial interface for data output and consumes approximately 9 mW of power during operation.
Feature Summary
- Integrates a 12-bit ADC, track-and-hold amplifier, clock oscillator, and serial interface logic within an 8-lead package.
- Supports single-supply operation from 2.7 V to 5.5 V, eliminating the need for external negative supplies or references.
- Includes an automatic power-down mode that activates after conversion completion to minimize energy consumption.
Applications
- Battery-powered portable instrumentation systems
- Industrial process control data acquisition
- Portable medical devices requiring low power consumption
Procurement Notes
Verify the specific suffix 'BNZ' against official documentation to confirm industrial temperature range compliance (-40°C to +85°C). Ensure the ordering information matches the exact package type required for the design. Cross-reference the manufacturer's current datasheet revision to validate all electrical specifications before finalizing procurement.
Selection Notes
Select this component when a compact 12-bit resolution is required with minimal external support circuitry. The integrated reference simplifies board layout compared to discrete solutions. Consider the 100 kHz throughput limit and serial interface timing constraints when designing the host microcontroller communication protocol.
Part Context
The AD7896 belongs to Analog Devices' family of fast, low-power sampling ADCs. It is designed to replace multi-component solutions by integrating essential functions into a small footprint. The BNZ variant specifically denotes the industrial temperature grade version housed in an 8-lead PDIP package.
