MCP6441/2/4

450 nA, 9 kHz Op Amp

Features:

Description:

The MCP6441/2/4 device is a single nanopower

operational amplifier (op amp), which has low

quiescent current (450 nA, typical) and rail-to-rail input

and output operation. This op amp is unity gain stable

and has a gain bandwidth product of 9 kHz (typical).

These devices operate with a single supply voltage as

low as 1.4V. These features make the family of op

amps well suited for single-supply, battery-powered

applications.

• Low Quiescent Current: 450 nA (typical)

• Gain Bandwidth Product: 9 kHz (typical)

• Supply Voltage Range: 1.4V to 6.0V

• Rail-to-Rail Input and Output

• Unity Gain Stable

• Slew Rate: 3V/ms (typical)

• Extended Temperature Range: -40°C to +125°C

• No Phase Reversal

The MCP6441/2/4 op amp is designed with Microchip’s

advanced CMOS process and offered in single

(MCP6441), dual (MCP6442), and quad (MCP6444)

configurations. All devices are available in the

extended temperature range, with a power supply

range of 1.4V to 6.0V.
