MCP6V91/1U/2/4 10 MHz, Zero-Drift Op Amps Features General Description High DC Precision: The Microchip Technology Incorporated -V Drift: 17 nV/C (maximum, V =5.5V) MCP6V91/1U/2/4 family of operational amplifiers OS DD provides input offset voltage correction for very low -V : 9 V (maximum) OS offset and offset drift. These devices have a gain -A : 126 dB (minimum, V =5.5V) OL DD bandwidth product of 10MHz (typical). They are - PSRR: 117 dB (minimum, V =5.5V) DD unity-gain stable, have virtually no 1/f noise and have - CMRR: 118 dB (minimum, V =5.5V) DD good Power Supply Rejection Ratio (PSRR) and -E : 0.24 V (typical), f = 0.1 Hz to 10 Hz Common Mode Rejection Ratio (CMRR). These ni P-P products operate with a single supply voltage as low as -E : 0.08 V (typical), f = 0.01 Hz to 1 Hz ni P-P 2.4V, while drawing 1.1mA/amplifier (typical) of Enhanced EMI Protection: quiescent current. - Electromagnetic Interference Rejection Ratio The MCP6V91/1U/2/4 family has enhanced EMI (EMIRR) at 1.8 GHz: 93 dB protection to minimize any electromagnetic Low Power and Supply Voltages: interference from external sources. This feature makes -I : 1.1 mA/amplifier (typical) Q it well suited for EMI-sensitive applications such as - Wide supply voltage range: 2.4V to 5.5V power lines, radio stations and mobile Small Packages: communications, etc. - Singles in SC70, SOT-23 The MCP6V91/1U/2/4 op amps are offered in single (MCP6V91 and MCP6V91U), dual (MCP6V92) and - Duals in MSOP-8, 2X3 TDFN quad (MCP6V94) packages. They were designed - Quads in TSSOP-14 using an advanced CMOS process.

DD As seen in Figures 1 and 2, the MCP6V91/1U op amps have excellent performance across temperature. The input offset voltage temperature drift (TC ) shown 1 is well within the specified maximum values of 17 nV/C at V = 5.5V and 24 nV/C at V =2.4V. DD DD This performance supports applications with stringent DC precision requirements. In many cases, it will not be necessary to correct for temperature effects (i.e., calibrate) in a design. In the other cases, the correction will be small. DS20005434B-page 2 2015-2016 Microchip Technology Inc. Input Offset Voltage (V) Input Offset Voltage (V)
