General Description
The Microchip Technology Incorporated
MCP6V91/1U/2/4 family of operational amplifiers
provides input offset voltage correction for very low
offset and offset drift. These devices have a gain
bandwidth product of 10 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
2.4V, while drawing 1.1 mA/amplifier (typical) of
quiescent current.
The MCP6V91/1U/2/4 family has enhanced EMI
protection 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.
The MCP6V91/1U/2/4 op amps are offered in single
(MCP6V91 and MCP6V91U), dual (MCP6V92) and
quad (MCP6V94) packages. They were designed
using an advanced CMOS process.

Note 1: These parameters were characterized using the circuit in Figure 1-6. In Figures 2-40 and 2-41, there is an IMD
tone at DC, a residual tone at 1 kHz and other IMD tones and clock tones. IMD is Referred to Input (RTI).
2: High gains behave differently; see Section 4.3.3 “Offset at Power-Up”.
3: tSTL and tODR include some uncertainty due to clock edge timing.
