Microchip Technology, Inc. 4.4 µA/Amplifier, 90 kHz Op Amp MCP6424

The Microchip’s MCP6421/2/4 operational amplifiers (op amps) has low input bias current (1 pA, typical) and rail-to-rail input and output operation. This family is unity gain stable and has a gain bandwidth product of 90 kHz (typical). These devices operate with a single-supply voltage as low as 1.8V, while only drawing 4.4 µA/amplifier (typical) of quiescent current. These features make the family of op amps well suited for photodiode amplifier, pH electrode amplifier, low leakage amplifier, and battery powered signal conditioning applications, etc. The MCP6424 family is offered in SOIC and TSSOP packages. All devices are designed using an advanced CMOS process and fully specified in extended temperature range from -40°C to +125°C. Additional Features Gain Bandwidth Product: 90 kHz (typical) Supply Voltage: 1.8V to 5.5V Supply Current: IQ = 4.4 µA (typical) Input Bias Current: Ibias = 1 pA (typical) EMIRR at 1.8 GHz: 97 dB (typical) Phase Margin: 57° (typical) Rail-to-Rail Input/Output Temperature Range: Extended: -40°C to +125°C Quad available in SOIC and TSSOP packages
