MAX44246

36V, Low-Noise, Precision, Dual Op Amp

General Description

Features

The MAX44246 is a 36V, ultra-precision, low-noise, low-

drift, dual operational amplifier that offers near-zero DC

offset and drift through the use of patented chopper

stabilized and auto-zeroing techniques. This method

constantly measures and compensates the input offset,

eliminating drift over time and temperature and the effect

of 1/f noise. This dual device features rail-to-rail outputs,

operates from a single 2.7V to 36V supply or dual 1.3ꢀV

to 1ꢁV supplies, and consumes only ꢂ.42mA per chan-

nel, with only 9nV/√Hz input-referred voltage noise.

S 2.7V to 36V Power-Supply Range

S Ultra-Low Input V : 5µV (max)

S Low 20nV/°C (max) of Offset Drift

S Low 9nV/√Hz noise at 1kHz

S 1µs Fast Settling Time

S 5MHz Gain-Bandwidth Product

S Rail-to-Rail Output

S Integrated EMI Filter

The IC is unity-gain stable with a gain-bandwidth product

of ꢀMHz. With excellent specifications such as offset

voltage of ꢀFV (max), drift of 2ꢂnV/NC (max), and

S Low 0.55mA Per Channel (max) Quiescent Current

S 8-Pin µMAX/SO Package

117nV

noise in ꢂ.1Hz to 1ꢂHz, the IC is ideally

P-P

suited for applications requiring ultra-low noise, and DC

precision such as interfacing with pressure sensors,

strain gauges, precision weight scales, and medical

instrumentation.

Ordering Information appears at end of data sheet.
