ADA4850-2YCPZ-R2

Overview

The ADA4850-2YCPZ-R2 is a dual-channel, high-speed voltage feedback operational amplifier featuring rail-to-rail output and ultralow power-down capabilities. It operates on single supplies from 2.7 V to 6 V or bipolar supplies up to ±5 V. Key electrical specifications include a 175 MHz bandwidth and a 220 V/µs slew rate at +5 V. The device draws 2.4 mA per amplifier in active mode and reduces current to less than 150 nA in power-down mode. It supports an operating temperature range of −40°C to +125°C.

Feature Summary

• Ultralow power-down mode reduces supply current to under 150 nA per amplifier for battery conservation.
• Rail-to-rail output stage swings within 80 mV of either supply rail under light loads.
• High-speed performance with 175 MHz bandwidth and 220 V/µs slew rate suitable for video applications.
• True single-supply operation allows input signals to extend below the negative rail.

Applications

• Portable multimedia players
• Video cameras
• Digital still cameras
• Consumer video equipment
• Clock buffers

Procurement Notes

Verify the specific ordering suffix (RL7) indicates tape and reel packaging when sourcing components. Confirm RoHS compliance status as indicated by the Z suffix in the part number. Ensure the supplier provides documentation matching the Rev D datasheet specifications for accurate parameter validation.

Selection Notes

Select this component for designs requiring high-speed signal processing with strict power constraints. The dual-channel configuration simplifies board space requirements compared to single-channel alternatives. Consider the 16-lead LFCSP package dimensions for thermal management and layout planning in compact enclosures.

Part Context

This part belongs to the ADA4850 family of high-speed op amps manufactured by Analog Devices Inc. The -2 designation identifies it as the dual-channel version, distinct from the single-channel ADA4850-1. It utilizes a 16-lead Lead Frame Chip Scale Package (LFCSP) for surface-mount assembly.

Replacement Considerations

ADA4850-2YCPZ-RL is a compatible alternative offering identical specifications in standard tube packaging rather than tape and reel.

FAQ

How is the power-down mode activated?

The power-down mode is activated by pulling the PD pin low, specifically to within 0.6 V of the negative supply voltage.

What is the maximum supply voltage for bipolar operation?

The device can operate on bipolar supplies up to ±5 V, provided the voltage difference between the negative supply and the power-down pin does not exceed 6 V.
