MCP6V01/2/3 300 µA, Auto-Zeroed Op Amps Features Description
• High DC Precision: The Microchip Technology Inc. MCP6V01/2/3 family of - V operational amplifiers has input offset voltage OS Drift: ±50 nV/°C (maximum) - V correction for very low offset and offset drift. These OS: ±2 µV (maximum) devices have a wide gain bandwidth product (1.3 MHz, - AOL: 130 dB (minimum) typical) and strongly reject switching noise. They are - PSRR: 130 dB (minimum) unity gain stable, have no 1/f noise, and have good - CMRR: 130 dB (minimum) PSRR and CMRR. These products operate with a - Eni: 2.5 µVP-P (typical), f = 0.1 Hz to 10 Hz single supply voltage as low as 1.8V, while drawing - E 300 µA/amplifier (typical) of quiescent current. ni: 0.79 µVp-p (typical), f = 0.01 Hz to 1 Hz • Low Power and Supply Voltages: The Microchip Technology Inc. MCP6V01/2/3 op amps - I are offered in single (MCP6V01), single with Chip Q: 300 µA/amplifier (typical) - Wide Supply Voltage Range: 1.8V to 5.5V Select (CS) (MCP6V03), and dual (MCP6V02). They are designed in an advanced CMOS process. • Easy to Use: - Rail-to-Rail Input/Output
