Description
The Microchip Technology Inc. MCP6001/2/4 family of
operational amplifiers (op amps) is specifically
designed for general-purpose applications. This family
has a 1 MHz Gain Bandwidth Product (GBWP) and 90°
phase margin (typical). It also maintains 45° phase
margin (typical) with a 500 pF capacitive load. This
family operates from a single supply voltage as low as
1.8V, while drawing 100 µA (typical) quiescent current.
Additionally, the MCP6001/2/4 supports rail-to-rail input
and output swing, with a common mode input voltage
range of V
DD
+ 300 mV to V
SS
– 300 mV. This family of
op amps is designed with Microchip’s advanced CMOS
process.
The MCP6001/2/4 family is available in the industrial
and extended temperature ranges, with a power supply
range of 1.8V to 6.0V.

Conditions
MCP6001/1R/1U/2/4 parts with date codes prior to December 2004 (week code 49) were tested to ±7 mV minimum/
maximum limits.
All parts with date codes November 2007 and later have been screened to ensure operation at
V
DD
= 6.0V. However, the other minimum and maximum specifications are measured at 1.8V and 5.5V.
