MCP6441/2/4 450 nA, 9 kHz Op Amp Features: Description: The MCP6441/2/4 device is a single nanopower Low Quiescent Current: 450 nA (typical) operational amplifier (op amp), which has low Gain Bandwidth Product: 9 kHz (typical) quiescent current (450 nA, typical) and rail-to-rail input Supply Voltage Range: 1.4V to 6.0V and output operation. This op amp is unity gain stable Rail-to-Rail Input and Output and has a gain bandwidth product of 9 kHz (typical). Unity Gain Stable These devices operate with a single supply voltage as low as 1.4V. These features make the family of op Slew Rate: 3V/ms (typical) amps well suited for single-supply, battery-powered Extended Temperature Range: -40C to +125C applications. No Phase Reversal The MCP6441/2/4 op amp is designed with Microchips Small Packages advanced CMOS process and offered in single (MCP6441), dual (MCP6442), and quad (MCP6444) Applications: configurations. All devices are available in the extended temperature range, with a power supply Portable Equipment range of 1.4V to 6.0V.
