ADA4851-4YRUZ

Overview

The ADA4851-4YRUZ is a quad, low-cost, high-speed voltage feedback operational amplifier with rail-to-rail output. It features a 130 MHz bandwidth and 375 V/µs slew rate. The device operates on a supply range of 2.7 V to 12 V, drawing 2.9 mA per channel at ±5 V. It includes a power-down mode for the single-channel variant (ADA4851-1), though this specific quad package lacks that pin. Input offset voltage is typically 0.6 mV, and it provides excellent video specifications including 0.08% differential gain.

Feature Summary

• Rail-to-rail output capability swings within 60 mV of either supply rail
• High-speed performance with 130 MHz bandwidth and 375 V/µs slew rate
• Low quiescent current consumption of approximately 2.5 mA per amplifier
• Excellent video specifications with low differential gain and phase distortion

Applications

• Automotive infotainment systems
• Consumer and professional video applications
• Video switchers and active filters
• Clock buffers

Procurement Notes

Verify the exact part number suffix against the manufacturer's ordering guide to ensure correct packaging and temperature grade. Confirm that the quad configuration matches the required circuit count, as single and dual variants exist with different pinouts. Check for automotive qualified versions if operating in harsh environments. Ensure ESD precautions are followed during handling.

Selection Notes

Select this component for general-purpose high-speed applications requiring rail-to-rail output swing. Consider the 14-lead TSSOP package for space-constrained designs. Evaluate thermal resistance requirements for high ambient temperatures. Compare input bias current and offset voltage specifications against system accuracy needs. Verify supply voltage compatibility with the 2.7 V to 12 V operating range.

Part Context

This quad amplifier belongs to the ADA4851 family, which also includes single (ADA4851-1) and dual (ADA4851-2) channels. The family shares core electrical characteristics but differs in pin counts and package options like SOT-23 and MSOP. The YRUZ suffix indicates the specific quad TSSOP package variant available from Analog Devices.
