Overview

Reduces Noise-Sensitive Precision Applications
- Low 9nV/√Hz Noise at 1kHz
- Integrated EMI Filter
Eliminates Cost of Calibration with Increased Accuracy and Patented Auto-Zero Circuitry
- Ultra-Low Input V_OS: 5µV (max)
- Low 20nV/°C (max) of Offset Drift
Suitable for High-Bandwidth Applications
- 1µs Fast Settling Time
- 5MHz Gain-Bandwidth Product
Low 0.55mA Per Channel (max) Quiescent Current
Wide Supply for High-Voltage Front-Ends
- 2.7V to 36V Supply Range
Rail-to-Rail Output

The MAX44241/MAX44243/MAX44246 are 36V, ultra- precision, low-noise, low-drift, single/quad/dual opera- tional amplifiers that offer near-zero DC offset and drift through the use of patented chopper stabilized and auto-zeroing techniques. This method constantly mea- sures and compensates the input offset, eliminating drift over time and temperature and the effect of 1/f noise. These single/quad/dual devices feature rail-to-rail out- puts, operate from a single 2.7V to 36V supply or dual ±1.35V to ±18V supplies, and consume only 0.42mA per channel, with only 9nV/√Hz input-referred voltage noise.

The ICs are available in 8-pin µMAX^® or SO packages and are rated over the -40°C to +125°C temperature range.

Product Details

The MAX44246 evaluation kit (EV kit) provides a proven design to evaluate the MAX44246 ultra-precision, low-noise, low-drift dual-operational amplifiers (op amps) in an 8-pin µMAX® package. The EV kit circuit is preconfigured as noninverting amplifiers, but can be adapted to other topologies by changing a few components.

The EV kit comes with a MAX44246AUA+ installed.
