MCP6024T-I/ST Descripción general
An operational amplifier (op amp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, typically, a single-ended output. It forms the basic building block of analog signal conditioning — used in sensor front-ends, active filters, transimpedance stages, and reference buffers — and is one of the most widely produced linear ICs in the world. The rail-to-rail family extends conventional op-amp input and output ranges to both supply rails, enabling full use of low-voltage ADC dynamic range and avoiding signal clipping in single-supply designs.
The MCP6024T-I/ST key features include: 10 MHz GBWP, 7 V/us slew rate, 1.0 mA quiescent current per amplifier, 0.5 mV input offset voltage (typical), RRIO swing, and a chip-select pin for multi-channel power saving. The TSSOP-14 footprint is widely accepted in industrial and consumer designs and offers better thermal behavior than smaller packages. The device is AEC-Q100 qualified when sourced in the VAO/automotive grade, and operates across the -40C to +85C industrial temperature range.
Architecturally, the MCP6024 uses Microchip's advanced CMOS process that balances low quiescent current with adequate bandwidth. The input stage uses a complementary differential pair supporting rail-to-rail common-mode range, and the output stage is a complementary CMOS push-pull capable of sourcing/sinking tens of milliamps for driving ADCs directly.
Typical applications include transducer signal conditioning (strain gauge, RTD, bridge sensors), battery-powered photomic devices, photodiode transimpedance amplifiers, audio summing/mixing stages, multi-pole active filters, and ADC input drivers in industrial data acquisition. It pairs naturally with the MCP3426 16-bit delta-sigma ADC or the MCP4728 quad DAC for complete analog signal chains.
When designing with the MCP6024T-I/ST, take care to bypass the supply pin with a 0.1 uF ceramic capacitor placed within 5 mm of the VDD pin. For low-noise designs, add a 10 uF bulk capacitor on the supply rail. Avoid running input traces parallel to high-current switching traces to preserve CMRR.

Aplicaciones típicas
MCP6024T-I/ST es adecuado para 6 aplicacións: Sensor Signal Conditioning, Photodiode Transimpedance Amplifier, Active Filter and Audio Preamp, Battery-Powered Instrumentation, ADC Input Driver / Reference Buffer, Automotive Sensor Interface (AEC-Q100 variant).
Sensor Signal Conditioning
The MCP6024T-I/ST's 10 MHz GBWP and 7 V/us slew rate make it ideal for conditioning bridge sensors, RTDs, and thermocouples in industrial data acquisition. The four-channel TSSOP package lets one IC handle multiple sensor channels simultaneously. With 0.5 mV input offset and 30 mA output drive, the amplifier preserves sensor accuracy across the -40C to +85C industrial temperature range. Place the op amp within 10 mm of the sensor to minimize noise pickup, and use a 1 nF to 10 nF feedback capacitor to limit gain peaking at higher frequencies.
Recomendado
Photodiode Transimpedance Amplifier
The MCP6024T-I/ST operates as a transimpedance amplifier (TIA) for photodiodes in smoke detectors, optical encoders, and pulse-oximetry front ends. With 10 MHz GBWP and CMOS input bias current, the amplifier provides wide dynamic range for converting photodiode current to voltage. The 30 mA output current enables fast settling into a downstream ADC, while rail-to-rail output maximizes signal swing for low-light detection. Use a feedback resistor of 100 kohm to 10 Mohm depending on photocurrent range, with a parallel capacitor of a few pF for stability.
Recomendado
Active Filter and Audio Preamp
The MCP6024T-I/ST implements Sallen-Key, multiple-feedback, and state-variable active filters at audio frequencies up to 100 kHz with low distortion. The four-channel package enables stereo two-pole filters or multi-band equalizer sections in one IC. Total harmonic distortion is low at 1 kHz/2 Vrms output, and rail-to-rail swing preserves dynamic range in 5 V designs. Add a 100 ohm series output resistor when driving long cables to prevent capacitive load oscillation, and pair with the MCP6024 for higher-power headphone output stages.
Recomendado
Battery-Powered Instrumentation
The MCP6024T-I/ST runs on a single 2.5 V to 5.5 V supply with 1.0 mA quiescent current per channel, making it well suited to portable instrumentation such as handheld multimeters and medical monitors. The four-channel TSSOP allows multiple measurement channels in a compact footprint, while CMOS input stages deliver picoampere-level bias current that does not load high-impedance sensors. For extended battery life, the chip-select pin on the MCP6024 (non-T) variant can power-down unused channels; pair with a low-IQ MCU such as PIC18 for system-level sleep management.
Recomendado
ADC Input Driver / Reference Buffer
The MCP6024T-I/ST serves as a precision ADC input driver, with its 10 MHz GBWP supporting 16-bit ADCs at full throughput and the 30 mA output current driving ADC input capacitors without slew-induced distortion. Rail-to-rail output swing maximizes ADC dynamic range, while the low 0.5 mV input offset preserves DC accuracy. Use a unity-gain buffer configuration for the reference voltage pin of successive-approximation ADCs, or as a differential-to-single-ended converter driving single-ended ADCs from bridge outputs.
Recomendado
Automotive Sensor Interface (AEC-Q100 variant)
The MCP6024T-I/STVAO variant qualifies to AEC-Q100 standards and operates reliably across -40C to +125C for automotive sensor interfaces including ECU analog front ends, battery management current sense amplifiers, and HVAC actuator drivers. Four channels per package reduce PCB area in space-constrained underhood electronics. The 10 MHz GBWP supports current-shunt monitor bandwidth for IGBT gate drive feedback, while 1.0 mA per channel IQ fits continuous-on body controller designs. Verify the VAO suffix when ordering to ensure AEC-Q100 compliance per Microchip product page.

Notas de diseño
Decouple the VDD pin with a 0.1 uF X7R ceramic capacitor placed within 5 mm of pin 4. For multi-channel designs switching at high frequencies, add a 10 uF bulk tantalum or ceramic capacitor on the supply rail. The TSSOP-14 ground pin (11) and the supply pin should be tied to a low-impedance ground plane to avoid supply-induced noise coupling into the input stages. Estimated: at full 4-channel output of 30 mA per channel, total supply current can reach 4 mA quiescent plus dynamic load.
Route input traces away from high-current switching traces to preserve CMRR. Use a guard trace tied to a low-impedance node (e.g., driven ground) around sensitive input pins to reduce leakage in high-impedance sensor applications. Place feedback components close to the inverting input pin and keep the non-inverting input trace short to avoid stray pickup. For TSSOP-14, exposed pad packages are not used; thermal relief is via the standard ground pin connection.
Avoid operating the input common-mode voltage beyond VDD or below VSS by more than 0.3 V, as the input ESD diodes can conduct and introduce distortion or latch-up. The MCP6024T-I/ST does not have phase reversal protection beyond the rails — verify the common-mode range for your specific application. Do not exceed 5.5 V supply; transients above 6 V can permanently damage the device. For driving large capacitive loads (>100 pF), insert a 50-100 ohm series resistor at the output to prevent oscillation.
