MAX44246：36V, Low-Noise, Precision, Single/Quad/Dual Op Amps

Precision, Low-Noise Performance in High-Voltage Applications

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.

Key Features 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 VOS: 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
