Dual, Rail-to-Rail, High-Output-Drive Op Amp in UCSP

The MAX4369 dual, high-output-drive op amp combines single-supply operation with high-output-current drive, rail-to-rail outputs in an ultra chip-scale package (UCSP™). The device is unity-gain stable to 3.5MHz and operates from a single 2.3V to 5.5V supply. The MAX4369 is guaranteed to source and sink up to 87mA with a 5V supply.

The MAX4369 is capable of delivering 120mW of continuous average power to a 16Ω load, or 75mW to a 32Ω load with 1% total harmonic distortion plus noise (THD+N), making the device ideal for portable audio applications.

The MAX4369 is specified over the extended temperature range (-40°C to +85°C) and is available in a tiny (1.5mm x 1.5mm) 9-bump UCSP.
