MAX9637AXA+T

The MAX9637AXA+T is a 3V/5V low power, low noise, CMOS, dual rail to rail I/O operational amplifier (op-amp) in 8 pin SC-70 package. This single supply, CMOS input op-amp has wide bandwidth at low quiescent current which makes it suitable for a broad range of battery powered applications. A combination of extremely low input bias currents, low input current noise and low input voltage noise allows interface to high impedance sources such as photo diode and piezoelectric sensors. The MAX9637 has maximized ratio of gain bandwidth (GBW) to supply current and it operates from single 2.1V to 5.5V supply at a typical quiescent supply current of 36μA. It is used in piezoelectric transducer amplifiers, smoke detectors and transimpedance amplifiers.

• Wide bandwidth of 1.5MHz and slew rate of 0.9V/µs
• Automotive temperature range from -40°C to 125°C
• Delivers low power, cost effective solution where low noise and low IBIAS are critical
• Input offset voltage of 0.01mV and ultra low bias current of ±0.1pA at TA = 25°C
• CMRR of 86dB (VSS <lt/> VCM <lt/> (VDD - 1.4V)) and PSRR of 100dB (VDD - VSS = 2.1V to 5.5V) at TA = 25°C
• Open loop gain of 124dB (VOUT = 0.25V from rails) and 120dB (VOUT = 0.4V from rails, RL = 600 ohm)
• Low input current noise density of 0.9fA/√Hz
• Extends battery life and saves board space
• Input offset voltage drift of 10μV/°C
