36V, Precision, Low-Noise,
Wide-Band Amplifier
General Description
The MAX9632 is a low-noise, precision, wide-band
operational amplifier that can operate in a very wide
+4.5V to +36V supply voltage range. The IC operates in
dual (±18V) mode.
The exceptionally fast settling time and low distortion
make the IC an excellent solution for precision acquisi-
tion systems. The rail-to-rail output swing maximizes the
dynamic range when driving high-resolution 24-bit Σ∆
ADCs even with low supply voltages.
The IC achieves 55MHz of gain-bandwidth product and
ultra-low 0.94nV/√Hz input voltage noise with only 3.9mA
of quiescent current.
The IC is offered in 8-pin SO and TDFN packages and
is rated for operation over the -40NC to +125NC tempera-
ture range.
