MCP6V31/1U/2/4 23 A, 300 kHz Zero-Drift Op Amps Features: Description: High DC Precision: The Microchip Technology Inc. MCP6V31/1U/2/4 family of operational amplifiers provides input offset -V Drift: 50 nV/C (maximum) OS voltage correction for very low offset and offset drift. -V : 8 V (maximum) OS These are low-power devices, with a gain bandwidth -A : 120 dB (minimum, V =5.5V) OL DD product of 300 kHz (typical). They are unity gain stable, - PSRR: 120 dB (minimum, V =5.5V) DD have virtually no 1/f noise, and have good Power - CMRR: 120 dB (minimum, V =5.5V) Supply Rejection Ratio (PSRR) and Common Mode DD -E : 1.0 V (typical), f = 0.1 Hz to 10 Hz Rejection Ratio (CMRR). These products operate with ni P-P a single supply voltage as low as 1.8V, while drawing -E : 0.33 V (typical), f = 0.01 Hz to 1 Hz ni P-P 23 A/amplifier (typical) of quiescent current. Low Power and Supply Voltages: The Microchip Technology Inc. MCP6V31/1U/2/4 op -I : 23 A/amplifier (typical) Q amps are offered in single (MCP6V31 and - Wide Supply Voltage Range: 1.8V to 5.5V MCP6V31U), dual (MCP6V32) and quad (MCP6V34) Small Packages: packages. They were designed using an advanced - Singles in SC70, SOT-23 CMOS process. - Duals in MSOP-8, 23 TDFN - Quads in TSSOP-14 Package Types Easy to Use: MCP6V31 MCP6V32 - Rail-to-Rail Input/Output SOT-23 MSOP - Gain Bandwidth Product: 300 kHz (typical) V V 1 5 V V 1 8 DD - Unity Gain Stable OUT DD OUTA V V 2 7 V 2 OUTB Extended Temperature Range: -40C to +125C SS INA V + V 3 6 V + 3 4 V INB INA IN IN V + V 4 5 INB Typical Applications: SS Portable Instrumentation MCP6V31U MCP6V32 Sensor Conditioning SC70, SOT-23 23 TDFN * Temperature Measurement V 1 8 V V + 1 5 V OUTA DD IN DD DC Offset Correction V 2 7 V V 2 EP INA OUTB SS Medical Instrumentation 9 V + 3 6 V V 3 4 V INA INB IN OUT V 4 5 V + SS INB Design Aids: MCP6V34 SPICE Macro Models TSSOP FilterLab Software V 1 14 V OUTD Microchip Advanced Part Selector (MAPS) OUTA 2 13 V V Analog Demonstration and Evaluation Boards IND INA V + 3 12 V + Application Notes INA IND V V 4 11 SS DD V + Related Parts: 5 10 V + INC INB V 6 9 V INB INC MCP6V01/2/3: Auto-Zeroed, Spread Clock V V 7 8 OUTC OUTB MCP6V06/7/8: Auto-Zeroed MCP6V26/7/8: Auto-Zeroed, Low Noise * Includes Exposed Thermal Pad (EP) see Table 3-1.
