OPA336P Visão geral
What is a CMOS operational amplifier? A CMOS operational amplifier uses complementary metal-oxide-semiconductor input and power structures to provide high input impedance, low input bias current, and low static power consumption. The OPA336P is a single-supply, micropower amplifier intended for portable instrumentation, sensor interfaces, battery-powered systems, and precision analog measurement. Its rail-to-rail input and output behavior helps preserve signal range near the supply rails, subject to the detailed datasheet limits.
According to the Texas Instruments OPA336 product information, the single, dual, and quad family versions have identical specifications for design flexibility. Verified highlights include 20 uA typical quiescent current per amplifier, 125 uV maximum offset voltage, 1 pA input bias current, and 115 dB high open-loop gain. The device is identified by distributors as a single amplifier in an 8-PDIP package.
The low 1 pA bias current is particularly useful with high-impedance sources because it reduces source-loading error. The 125 uV maximum offset is valuable for low-level sensor and current-feedback measurements where input-referred error affects accuracy. Its micropower architecture supports longer battery life, while the 8-pin PDIP package remains straightforward for through-hole prototypes and manually assembled boards.
Typical uses include battery-powered sensor interfaces, medical and industrial instrumentation, low-current signal conditioning, photodiode preamplification, portable measurement systems, and general low-power analog filtering. The circuit role is usually a voltage amplifier, buffer, or active-filter element. Designers should verify supply range, input common-mode limits, output swing, stability, noise, slew rate, and temperature limits against the manufacturer datasheet before production release.
A key design consideration is that micropower does not eliminate all layout and signal-integrity requirements. Keep feedback components close to the amplifier, maintain a low-impedance return path, and account for input-bias-current error and output-capacitance stability. This page combines verified manufacturer and distributor information with practical selection guidance, while missing numerical parameters are explicitly marked for engineering follow-up.

Aplicações típicas
OPA336P é adequado para 6 aplicaçãos: Battery-Powered Sensor Interface, High-Impedance Photodiode Amplifier, Portable Instrumentation, Precision Active Filter, Low-Power Data Acquisition, Industrial Current and Voltage Monitoring.
Battery-Powered Sensor Interface
OPA336P fits low-power sensor front ends because the verified 20 uA typical quiescent current limits standing power, while 1 pA input bias current helps preserve signals from high-impedance sources. Place the amplifier close to the sensor and use short, shielded signal paths to reduce leakage and interference. The 125 uV maximum offset is useful for low-level measurements, but the design must still verify supply range, input common-mode limits, output swing, bandwidth, and sensor impedance before release.
Recomendado
High-Impedance Photodiode Amplifier
OPA336P is a reasonable candidate for photodiode and other high-impedance current sources because its verified 1 pA input bias current minimizes input-current loading. Use the amplifier in a transimpedance or guarded-input arrangement, with the feedback resistor and compensation capacitor placed close to the device. The practical limit is set by the required bandwidth, input capacitance, leakage, resistor value, and stability conditions, which must be taken from the complete OPA336 datasheet.
Recomendado
Portable Instrumentation
OPA336P supports portable instrumentation when battery life and signal-chain accuracy are primary concerns. Its 20 uA typical quiescent current reduces amplifier overhead, and the 125 uV maximum input offset provides a defined starting point for precision error budgeting. For instrumentation, compare the full signal bandwidth and noise requirements against the family datasheet, use clean grounding, and account for resistor and reference errors rather than relying on amplifier specifications alone.
Recomendado
Precision Active Filter
OPA336P can be used in precision active-filter and gain stages where low input bias current and moderate open-loop gain are useful. Its 115 dB typical open-loop gain supports accurate closed-loop behavior when the feedback network is well designed. Check gain-bandwidth product, slew rate, output swing, noise, and capacitive-load stability before selecting component values. Keep the feedback network compact and maintain a low-impedance reference return to avoid introducing errors unrelated to the amplifier itself.
Recomendado
Low-Power Data Acquisition
OPA336P is suited to low-power data-acquisition chains that condition sensor outputs before conversion. Its verified 20 uA typical quiescent current helps keep the analog front end from dominating battery consumption, and its 1 pA input bias current is helpful with high-impedance sensor nodes. The designer should verify input bandwidth, settling behavior, common-mode range, supply voltage, output drive, and ADC input requirements in the manufacturer documentation before finalizing the signal chain.
Recomendado
Industrial Current and Voltage Monitoring
OPA336P can support low-current industrial monitoring circuits when the measured source has high impedance or the system must conserve power. The verified 125 uV maximum offset and 1 pA input bias current help reduce input-referred error, but the complete accuracy budget must include resistor tolerance, sensor error, leakage, noise, and temperature drift. Use a protected input network and verify industrial supply and temperature requirements separately; the supplied data does not state an AEC-Q100 qualification.

Notas de projeto
OPA336P is intended for low-power precision signal conditioning, so board leakage and contamination can matter as much as the stated 1 pA input bias current. Keep sensitive input traces short, use guarding where appropriate, clean the board and connectors, and avoid routing high-impedance nodes next to switching or digital signals. Confirm leakage, stability, and capacitance limits against the manufacturer datasheet before relying on a high-impedance design.
Place the amplifier, feedback resistors, and compensation capacitor close together and connect the return path directly to the device ground pin. Avoid long high-impedance traces and excessive parallel copper that can increase leakage or parasitic capacitance. For the 8-pin PDIP package, follow the official package drawing and pinout because individual pin assignments were not included in the supplied verified data.
The verified 20 uA typical quiescent current is useful for battery designs, but it does not include load current or dynamic output current. Estimated quiescent supply power is approximately supply voltage multiplied by 20 uA; at 3.3 V this is 66 uW before load current. Check the complete operating-current specification, output swing, supply range, and startup behavior in the OPA336 documentation.
Do not select a replacement from the OPA336 family name alone. Confirm package dimensions, pin numbering, supply range, input common-mode range, output swing, offset voltage, input bias current, bandwidth, slew rate, noise, and capacitive-load stability. The supplied cross-reference results identify related MPNs but do not provide enough verified data to establish full drop-in equivalence.
Informações de conformidade
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than inferred.
