MCP6V71/1U/2/4
170 µA, 2 MHz Zero-Drift Op Amps
Features
Description
• High DC Precision:
The Microchip Technology Inc. MCP6V71/1U/2/4
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 2 MHz (typical). They are unity-gain stable,
have virtually 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 2V, while drawing
170 µA/amplifier (typical) of quiescent current.
- VOS Drift: ±15 nV/°C (maximum, VDD = 5.5V)
- VOS: ±8 µV (maximum)
- AOL: 126 dB (minimum, VDD = 5.5V)
- PSRR: 115 dB (minimum, VDD = 5.5V)
- CMRR: 117 dB (minimum, VDD = 5.5V)
- Eni: 0.45 µVP-P (typical), f = 0.1 Hz to 10 Hz
- Eni: 0.15 µVP-P (typical), f = 0.01 Hz to 1 Hz
• Enhanced EMI Protection:
The MCP6V71/1U/2/4 family has enhanced EMI pro-
tection to minimize any electromagnetic interference
from external sources. This feature makes it well suited
for EMI sensitive applications such as power lines,
radio stations and mobile communications, etc.
- Electromagnetic Interference Rejection Ratio
(EMIRR) at 1.8 GHz: 96 dB
• Low Power and Supply Voltages:
- IQ: 170 µA/amplifier (typical)
- Wide Supply Voltage Range: 2V to 5.5V
• Small Packages:
The Microchip Technology Inc. MCP6V71/1U/2/4 op
amps are offered in single (MCP6V71 and
MCP6V71U), dual (MCP6V72) and quad (MCP6V74)
packages. They were designed using an advanced
CMOS process.
- Singles in SC70, SOT-23
- Duals in MSOP-8, 2x3 TDFN
- Quads in TSSOP-14
• Easy to Use:
- Rail-to-Rail Input/Output
