ADA4850-1YCPZ-RL

Overview

The ADA4850-1YCPZ-RL is a 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 parameters include a 175 MHz bandwidth at +5 V, a 220 V/µs slew rate, and a quiescent current of 2.4 mA per amplifier. In power-down mode, supply current drops below 150 nA. The device supports an extended operating temperature range of −40°C to +125°C and is housed in an 8-lead LFCSP package.

Feature Summary

• Ultralow power-down mode reduces supply current to less than 150 nA for battery-powered applications.
• Rail-to-rail output stage swings within 80 mV of either supply rail under light loads.
• True single-supply operation allows input signals to extend 200 mV below the negative rail.

Applications

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

Procurement Notes

Verify the specific ordering suffix RL against the manufacturer's official documentation to confirm reel packaging specifications. Ensure compatibility with the required thermal management standards for the 8-lead LFCSP package. Confirm RoHS compliance status as indicated by the Z suffix in the part number before finalizing procurement orders.

Selection Notes

Select this component for designs requiring high-speed signal processing with strict power constraints. The ultralow power-down feature makes it suitable for portable devices where standby current must be minimized. Verify that the application load requirements align with the rail-to-rail output swing capabilities and that the supply voltage remains within the specified 2.7 V to 6 V range.

Part Context

This component belongs to the ADA4850 family of high-speed op amps manufactured by Analog Devices Inc. The family includes single-channel (ADA4850-1) and dual-channel (ADA4850-2) variants. All members share similar performance characteristics, including high slew rates and low power consumption, designed for general-purpose high-speed applications.

FAQ

How is the power-down mode activated?

The power-down mode is activated by bringing the power-down pin to within 0.6 V of the negative supply voltage, reducing the supply current to less than 150 nA.

What is the input common-mode voltage range?

The input common-mode voltage range extends 200 mV below the negative supply voltage to within 2.2 V of the positive supply voltage.
