ADA4850-1YCPZ-R2

Overview

The ADA4850-1YCPZ-R2 is a high-speed, voltage feedback operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output capability and an ultralow power-down mode. The device operates on single supplies ranging from 2.7 V to 6 V or bipolar supplies up to ±5 V. Key electrical parameters include a −3 dB bandwidth of 175 MHz at +5 V supply, a slew rate of 220 V/µs, and a settling time of 85 ns to 0.1%. Quiescent current is 2.9 mA per amplifier, reducing to less than 150 nA in power-down mode. The input offset voltage is typically 0.6 mV with a drift of 4 µV/°C. The component is housed in an 8-Lead Lead Frame Chip Scale Package (LFCSP) measuring 3 mm × 3 mm.

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 includes 175 MHz bandwidth and 220 V/µs slew rate.
• 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 against official documentation to confirm package type and reel specifications. Ensure compatibility with the required temperature range and RoHS compliance status before integration. Confirm pinout alignment with the 8-Lead LFCSP layout during schematic capture. Validate that the power-down control logic matches the specified voltage thresholds for enable and disable states.

Selection Notes

Select this component for designs requiring high bandwidth and low quiescent current in portable devices. Consider the 175 MHz bandwidth and 220 V/µs slew rate for fast signal processing tasks. Evaluate the ultralow power-down feature for extending battery life in mobile equipment. Ensure the 80 mV output swing meets the dynamic range requirements of the downstream circuitry.

Part Context

This part belongs to the ADA4850 family of high-speed, rail-to-rail output op amps. The family includes single-channel (ADA4850-1) and dual-channel (ADA4850-2) variants. All members share similar electrical characteristics, including high speed and ultralow power-down functionality. The YCPZ suffix indicates the 8-Lead LFCSP package option compliant with RoHS standards.

Replacement Considerations

The ADA4850-1YCPZ-RL7 is a listed alternative in the ordering guide for the same package and temperature range.

FAQ

How is the power-down mode activated?

The amplifier enters power-down mode when the power-down pin is brought 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.
