Analog Devices (MAX44246ASA+) Operational Amplifier, Precision

Operational Amplifier, Precision, Rail to Rail Output, 2 Amplifier, 5 MHz, 3.8 V/µs Product Overview The MAX44246ASA+ is a low noise, ultra precision dual operational amplifier (op-amp) in 8 pin NSOIC package. This low drift op-amp offers near zero DC offset and drift through the use of patented chopper stabilized and auto zeroing techniques. This method constantly measures and compensates input offset by eliminating drift over time and temperature and effect of 1/f noise. Increased accuracy and patented auto zero circuitry eliminates the cost of calibration. The MAX44246 consumes only 0.42mA per channel with only 9nV/√Hz at 1KHz input referred voltage noise. The device is used in transducer amplifiers, load cell, amplifiers, PLC, analogue I/O modules and battery powered equipments. Supply voltage range from ± 1.35V to ± 18V, 2.7V to 36V Operating temperature range from -40°C to 125°C Integrated EMI filter Input bias current of 300pA and input offset current of 600pA at TA = +25°C, VDD = 30V Ultra low input offset voltage of 1µV and low input offset voltage drift of 1nV/°C at VDD = 30V PSRR of 166dB (TA = +25°C) and CMRR of 166dB at VDD = 30V Suitable for high bandwidth applications 5MHz gain bandwidth product and 3.8V/µs slew rate at VDD = 30V Open loop gain of 168dB at VDD = 30V Fast settling time of 1µs at VDD = 10V Applications Signal Processing, Sensing & Instrumentation Product Information No. of Amplifiers: 2 Amplifier Bandwidth: 5MHz Slew Rate: 3.8V/µs Supply Voltage Range: ± 1.35V to ± 18V, 2.7V to 36V Amplifier Case Style: NSOIC No. of Pins: 8Pins Operating Temperature Min: -40°C Operating Temperature Max: 125°C MSL: MSL 1 - Unlimited
