MCP6001T-I/OT 1 MHz Low-Power Operational Amplifier SOT23-5

MCP6001T-I/OT 1 MHz Low-Power Operational Amplifier SOT23-5 is an essential single-supply op-amp that provides designers with a compact, high-performance solution for battery-powered and portable applications. This specific operational amplifier features a Gain Bandwidth Product (GBWP) of 1 MHz and a low quiescent current of just 100 μA. Consequently, it delivers an excellent balance between speed and power consumption. The rail-to-rail input and output swing capabilities maximize the dynamic range, thus allowing the amplifier to operate effectively with power supplies as low as 1.8V. Furthermore, its small SOT-23 package makes the MCP6001T-I/OT an ideal choice for space-constrained industrial and consumer electronics.

Key Features:

• Low Quiescent Current: It draws only 100 μA (typical) of supply current, significantly extending the battery life in portable devices.
• Rail-to-Rail Operation: The device features both Rail-to-Rail Input (RRI) and Rail-to-Rail Output (RRO), which maximizes the available dynamic signal range across the full supply voltage.
• Wide Operating Voltage: The op-amp operates reliably from a single supply voltage ranging from 1.8 V to 5.5 V, supporting standard logic and battery voltages.
• Gain Bandwidth Product (GBWP): It offers a 1 MHz bandwidth, enabling the amplifier to handle low-frequency signal conditioning, filtering, and buffering tasks efficiently.
• Small Form Factor: The tiny 5-pin SOT-23 package minimizes board space, which is critical for modern compact PCB designs.

Pinout and Wiring:

• Pin 1 (V_OUT): The output pin of the operational amplifier. Connect this to the next stage of your circuit.
• Pin 2 (V_IN−): The inverting input pin. Connect feedback components (resistors, capacitors) here for gain setting.
• Pin 3 (V_IN+): The non-inverting input pin. Apply the signal reference or input voltage here.
• Pin 4 (V_SS): The negative supply voltage pin. Usually, connect this pin to ground (GND) in a single-supply configuration.
• Pin 5 (V_DD): The positive supply voltage pin. Always ensure you bypass this pin with a ceramic capacitor (0.1 μF recommended) placed close to the device.
