Detailed Description

Dual, high-speed, low-noise, fully differential amplifier optimized for precision ADC driving. Adjustable gain with external resistors and a VOCM pin for accurate output common-mode control. Ideal for single-supply operation around 3.3 V to 5 V, with excellent linearity and low distortion. Compact LFCSP package for space-constrained designs.

Key Features

Dual fully differential amplifier for balanced signal paths

Optimized ADC driver performance with very low distortion and noise

Adjustable gain via external resistors; stable across wide gain settings

VOCM input enables precise output common-mode control for dc coupling

Wide input common-mode range; supports single-supply operation

High bandwidth and fast slew rate for IF/baseband signals

Excellent SFDR and IMD; designed for high-resolution converters

Rail-to-rail differential output swing (within headroom limits)

Compact LFCSP with exposed thermal pad for reliable heat dissipation

RoHS-compliant, lead-free packaging

Key Advantages

Superior dynamic performance for 14–16-bit ADCs and beyond

Differential architecture minimizes even-order distortion and common-mode noise

Simple interface to modern ADCs; easy VOCM biasing and gain setting

Low noise floor supports high SNR systems

Saves board space and reduces BOM with dual-channel integration

Robust thermal performance in compact footprint

Stable, predictable behavior across temperature and supply variations

Packaging

Type: LFCSP (Lead Frame Chip Scale Package)

Material: Molded plastic over copper lead frame; lead-free, RoHS compliant

Size: Compact footprint, commonly around 4 mm x 4 mm with low profile height

Pin configuration: Multi-lead LFCSP with differential inputs/outputs per channel, VOCM, supply pins, and exposed thermal pad (see datasheet for exact pinout)

Exposed pad: Yes, for improved thermal conductivity; recommended to solder to PCB ground plane

Thermal characteristics: Low thermal resistance with proper pad soldering and vias; typical θJA in the tens of °C/W range depending on board design

Electrical properties: High bandwidth, low input noise density, high linearity; designed for precision ADC drive

Package / Case: 831 (manufacturer package/case reference)

Moisture sensitivity: Standard MSL for LFCSP; follow reflow and storage guidelines

Lifecycle

Status: Active and widely used; not nearing discontinuation based on current industry status
