MAX44244/MAX44245/

MAX44248

36V, Precision, Low-Power, 90μA,

Single/Quad/Dual Op Amps

General Description

Beneﬁts and Features

● Reduces Power for Sensitive Precision Applications

The MAX44244/MAX44245/MAX44248 family of parts

provide ultra-precision, low-noise, zero-drift single/quad/

dual operational amplifiers featuring very low-power

operation with a wide supply range. The devices

incorporate a patented auto-zero circuit that constantly

measures and compensates the input offset to eliminate

drift over time and temperature as well as the effect of 1/f

noise. These devices also feature integrated EMI filters

to reduce high-frequency signal demodulation on the

output. The op amps operate from either a single 2.7V to

36V supply or dual ±1.35V to ±18V supply. The devices

are unity-gain stable with a 1MHz gain-bandwidth product

and a low 90µA supply current per amplifier.

• Low 90µA Quiescent Current per Ampliﬁer

● Eliminates the Cost of Calibration with Increased

Accuracy with Maxim’s Patented Autozero Circuitry

• Very Low Input Voltage Oﬀset 7.5µV (max)

• Low 30nV/°C Oﬀset Drift (max)

● Low Noise Ideal for Sensor Interfaces and

Transmitters

• 50nV/√Hz at 1kHz

• 0.5µV

from 0.1Hz to 10Hz

P-P

● 1MHz Gain-Bandwidth Product

• EMI Suppression Circuitry

The low offset and noise specifications and high supply

range make the devices ideal for sensor interfaces and

transmitters.

● Rail-to-Rail Output

● Wide Supply for High-Voltage Front Ends

• 2.7V to 36V Supply Range

The devices are available in µMAX , SO, SOT23, and

● µMAX, SO, SOT23, TSSOP Packages

TSSOP packages and are specified over the -40°C to

+125°C automotive operating temperature range.

Ordering Information appears at end of data sheet.
