ADA4850-2YCPZ-RL

Overview

The ADA4850-2YCPZ-RL 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 parameters include a 175 MHz gain-bandwidth product, 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.

Feature Summary

• Ultralow power-down mode reduces supply current to less than 150 nA per amplifier for battery-powered applications.
• 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 general-purpose high-speed applications.
• 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 that the ordering suffix matches the required reel quantity (e.g., RL vs. RL7) as specified in the manufacturer's ordering guide. Confirm the package option corresponds to the 16-Lead Lead Frame Chip Scale Package (CP-16-21). Ensure compliance with RoHS standards if required by the design specifications.

Selection Notes

Select this component when low power consumption during standby is critical alongside high-speed signal processing. The dual-channel configuration is ideal for stereo video or differential signaling applications. Consider the 16-lead LFCSP package for compact board layouts requiring surface-mount installation.

Part Context

This part belongs to the ADA4850 family of high-speed op amps designed for versatility and low cost. The ADA4850-2 variant provides two independent amplifiers in a single package, sharing the same power supply and ground connections while maintaining separate inputs and outputs for distinct signal paths.

FAQ

How is the power-down mode activated?

The amplifier enters power-down mode when the PD pin is brought to within 0.6 V of the negative supply voltage. To ensure proper operation, the power-down pins should not be left floating.

What is the maximum supply voltage for bipolar operation?

The device can operate on bipolar supplies up to ±5 V. However, the voltage difference between the negative supply and the POWER DOWN pin must not exceed 6 V to prevent damage.
