Dual, Rail-to-Rail, High-Output-Drive
Op Amp in UCSP
General Description
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 con-
tinuous 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 tempera-
ture range (-40°C to +85°C) and is available in a tiny
(1.5mm x 1.5mm) 9-bump UCSP.
