1. Description

The Microchip Technology Inc. MCP604-E/SL family of low-power operational amplifiers (op amps) are offered in single (MCP601), single with Chip Select (CS) (MCP603), dual (MCP602), and quad (MCP604) configurations. These op amps utilize an advanced CMOS technology that provides low bias current, highspeed operation, high open-loop gain, and rail-to-rail output swing. This product offering operates with a single supply voltage that can be as low as 2.7V, while drawing 230 µA (typical) of quiescent current per amplifier. In addition, the common mode input voltage range goes 0.3V below ground, making these amplifiers ideal for single-supply operation. These devices are appropriate for low power, battery operated circuits due to the low quiescent current, for A/D convert driver amplifiers because of their wide bandwidth or for anti-aliasing filters by virtue of their low input bias current. The MCP601, MCP602, and MCP603 are available in standard 8-lead PDIP, SOIC, and TSSOP packages. The MCP601 and MCP601R are also available in a standard 5-lead SOT-23 package, while the MCP603 is available in a standard 6-lead SOT-23 package. The MCP604 is offered in standard 14-lead PDIP, SOIC, and TSSOP packages. The MCP601/1R/2/3/4 family is available in the Industrial and Extended temperature ranges and has a power supply range of 2.7V to 6.0V.

4. PIN DESCRIPTIONS

    1. Analog Outputs

        The op amp output pins are low-impedance voltage sources.

    2. Analog Inputs

        The op amp non-inverting and inverting inputs are highimpedance CMOS inputs with low bias currents.

    3. Chip Select Digital Input

        This is a CMOS, Schmitt-triggered input that places the part into a low power mode of operation.

    4. Power Supply Pins

        The positive power supply pin (VDD) is 2.5V to 6.0V higher than the negative power supply pin (VSS). For normal operation, the other pins are at voltages between VSS and VDD. Typically, these parts are used in a single (positive) supply configuration. In this case, VSS is connected to ground and VDD is connected to the supply. VDD will need bypass capacitors.
