ADA4850-2YCPZ-RL7

Overview

The ADA4850-2YCPZ-RL7 is a dual-channel, high-speed voltage feedback operational amplifier with 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 −3 dB bandwidth, 220 V/μs slew rate, and 85 ns settling time to 0.1%. Quiescent current is 2.4 mA per amplifier, dropping to less than 150 nA in power-down mode. The device features an input offset voltage of 0.6 mV and 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 allows signal swing within 80 mV of either supply rail.
• High-speed performance includes 175 MHz bandwidth and 220 V/μs slew rate.
• True single-supply operation with input common-mode range extending 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 reel packaging when sourcing. Confirm RoHS compliance status via manufacturer documentation. Ensure the LFCSP-16 package dimensions match PCB footprint requirements. Check thermal resistance specifications for adequate heat dissipation in the target application environment.

Selection Notes

Select this component for applications requiring high bandwidth and low quiescent current in portable devices. Consider the rail-to-rail output capability for maximizing dynamic range in low-voltage systems. Evaluate the power-down feature if extended battery life is critical. Verify that the 16-lead LFCSP package fits the available board space.

Part Context

This part belongs to the ADA4850 family of high-speed op amps manufactured by Analog Devices. The '2' designation indicates a dual-amplifier configuration, while 'YCPZ' specifies the 16-lead Lead Frame Chip Scale Package (LFCSP) variant. The 'RL7' suffix denotes tape and reel packaging for automated assembly.

FAQ

How is the power-down mode activated?

The power-down mode is activated by bringing the PD pin 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 amplifiers 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 avoid damage.
