AD8476BCPZ-RL

Instrumentation, Op Amps, Buffer Amps Overview

The AD8476BCPZ-RL is a low power, unity gain, fully differential amplifier and ADC driver manufactured by Analog Devices Inc. It features integrated precision gain resistors for a fixed gain of 1 V/V. Key electrical parameters include a 6 MHz small signal bandwidth, a 10 V/µs slew rate, and a supply current of 330 µA at +5 V. The device operates on single supplies from 3 V to 18 V or dual supplies from ±1.5 V to ±9 V. It offers robust overvoltage protection up to 18 V beyond the supply rails. The component is housed in a 16-lead LFCSP package and is specified for operation over a temperature range of -40°C to +125°C.

• VOCM pin allows independent adjustment of the output common-mode voltage to match ADC input ranges.
• Robust overvoltage protection tolerates input voltages up to 18 V beyond the supply rails without damage.
• Rail-to-rail outputs ensure maximum dynamic range when driving precision analog-to-digital converters.

Instrumentation, Op Amps, Buffer Amps Applications

• Driving switched capacitor and Sigma-Delta ADCs
• Single-ended-to-differential signal conversion
• Differential instrumentation amplifier building blocks
• Battery-powered instruments requiring low power consumption

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'R7' against the datasheet ordering guide to confirm reel packaging specifications. Ensure the B grade performance metrics align with system requirements. Confirm the 16-lead LFCSP package dimensions match the PCB footprint. Validate that the operating temperature range meets environmental constraints. Check for moisture sensitivity levels if storage conditions are critical.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a precision unity gain differential amplifier is required for ADC interfacing. The low power consumption makes it suitable for battery-operated systems. The VOCM control feature simplifies level shifting for various ADC input ranges. Consider the 6 MHz bandwidth and 10 V/µs slew rate for signal frequencies up to several hundred kilohertz. The high overvoltage tolerance provides protection against industrial input transients.
