MCP6031/2/3/4 0.9 µA, High Precision Op Amps Features Description
• Rail-to-Rail Input and Output The Microchip Technology Inc. MCP6031/2/3/4 family • Low Offset Voltage: ±150 µV (maximum) of operational amplifiers (op amps) operate with a • Ultra Low Quiescent Current: 0.9 µA (typical) single supply voltage as low as 1.8V, while drawing ultra low quiescent current per amplifier (0.9 µA, • 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 µV, maximum) and rail-to-rail input and output • Unity Gain Stable operation. This combination of features supports • Chip Select (CS) capability: MCP6033 battery-powered and portable applications. • Extended Temperature Range: The MCP6031/2/3/4 family is unity gain stable and has - -40°C to +125°C a gain bandwidth product of 10 kHz (typical). These • No Phase Reversal specs make these op amps appropriate for low fre- quency applications, such as battery current
