MCP6031/2/3/4 0.9 A, High Precision Op Amps Features Description Rail-to-Rail Input and Output The Microchip Technology Inc. MCP6031/2/3/4 family of operational amplifiers (op amps) operate with a Low Offset Voltage: 150 V (maximum) single supply voltage as low as 1.8V, while drawing Ultra Low Quiescent Current: 0.9 A (typical) ultra low quiescent current per amplifier (0.9A, Wide Power Supply Voltage: 1.8V to 5.5V typical). This family also has low input offset voltage Gain Bandwidth Product: 10 kHz (typical) (150 V, maximum) and rail-to-rail input and output Unity Gain Stable operation. This combination of features supports battery-powered and portable applications. Chip Select (CS) capability: MCP6033 Extended Temperature Range: The MCP6031/2/3/4 family is unity gain stable and has a gain bandwidth product of 10 kHz (typical). These - -40C to +125C specs make these op amps appropriate for low fre- No Phase Reversal quency applications, such as battery current monitoring and sensor conditioning. Applications The MCP6031/2/3/4 family is offered in single Toll Booth Tags (MCP6031), single with power saving Chip Select (CS) Wearable Products input (MCP6033), dual (MCP6032), and quad (MCP6034) configurations. Battery Current Monitoring Sensor Conditioning The MCP6031/2/3/4 family is designed with Micro- Battery Powered chips advanced CMOS process. All devices are available in the extended temperature range, with a power supply range of 1.8V to 5.5V.
