MCP6V11/1U
7.5 µA, 80 kHz Zero-Drift Op Amps
Features
Description
• High DC Precision:
The Microchip Technology Inc. MCP6V11/1U family of
operational amplifiers provides input offset voltage
correction for very low offset and offset drift. These are
low power devices, with a gain bandwidth product of
80 kHz (typical). They are unity gain stable, have no 1/f
noise, and have good Power Supply Rejection Ratio
(PSRR) and Common Mode Rejection Ratio (CMRR).
These products operate with a single supply voltage as
low as 1.6V, while drawing 7.5 µA/amplifier (typical) of
quiescent current.
- VOS Drift: ±50 nV/°C (maximum)
- VOS: ±8 µV (maximum)
- AOL: 112 dB (minimum, VDD = 5.5V)
- PSRR: 118 dB (minimum, VDD = 5.5V)
- CMRR: 119 dB (minimum, VDD = 5.5V)
- Eni: 2.1 µVP-P (typical), f = 0.1 Hz to 10 Hz
- Eni: 0.67 µVP-P (typical), f = 0.01 Hz to 1 Hz
• Low Power and Supply Voltages:
- IQ: 7.5 µA/amplifier (typical)
The Microchip Technology Inc. MCP6V11/1U op amps
are offered in single (MCP6V11 and MCP6V11U)
packages. They were designed using an advanced
CMOS process.
- Wide Supply Voltage Range: 1.6V to 5.5V
• Small Packages
- Singles in SC70, SOT-23
• Easy to Use:
