OP07CDR 概述
An operational amplifier is an active analog building block used to amplify, buffer, filter, or compare differential signals. Within the broader hierarchy, the OP07CDR is a voltage-feedback precision op amp, a type of analog amplifier used in measurement and control systems. Its eight-pin SOIC package supports conventional surface-mount PCB assembly.
The verified distributor data identifies the OP07CDR as a standard general-purpose amplifier with one circuit, 600 kHz gain-bandwidth product, and 0.3 V/us slew rate. The device operates across approximately plus or minus 3 V to plus or minus 18 V supplies, with a 0 to 70 C temperature range reported by the verified component listing. The official Texas Instruments product page describes the device as a low-offset voltage single operational amplifier with external input-offset-voltage adjustment.
The low-offset architecture is useful when amplification is applied to small sensor signals or precision measurement nodes, where input-referred offset can become a meaningful error. The wide supply range allows operation from single-supply-compatible systems when appropriate biasing is used through the dual-supply-compatible implementation. The 600 kHz bandwidth and 0.3 V/us slew rate suit general-purpose precision signal paths rather than high-speed video or RF amplification.
Typical uses include instrumentation amplifiers, current-to-voltage conversion, low-level sensor interfaces, analog measurement chains, laboratory test equipment, and precision feedback networks. In these applications, the external offset adjustment allows board-level calibration when offset control is needed.
Designers should provide stable decoupling close to the supply pins, verify input and output common-mode limits against the selected supply, and keep feedback components close to the amplifier for reduced parasitic effects. The TI product page identifies the OP07CDR as active and available in an SOIC package. This page consolidates verified distributor specifications, lifecycle information, sourcing data, and application guidance for engineers evaluating OP07CDR.

典型应用
OP07CDR 适用于 6 应用s: Precision Instrumentation Signal Conditioning, Sensor Interface and Current-to-Voltage Conversion, Laboratory Measurement Equipment, Analog Feedback and Control Loops, Data Acquisition and Analog Filtering, Audio and Low-Level Analog Processing.
Precision Instrumentation Signal Conditioning
OP07CDR fits low-level instrumentation front ends where offset error must be controlled and calibration is valuable. Its verified 600 kHz gain-bandwidth product and 0.3 V/us slew rate provide useful bandwidth for general measurement channels, while the external input-offset adjustment supports board-level trim. Place the amplifier close to the sensor or converter and use short feedback paths to reduce parasitic pickup. Confirm the required common-mode and output-swing limits against the selected supply before finalizing the gain network.
推荐
Sensor Interface and Current-to-Voltage Conversion
Use OP07CDR as the analog gain stage for small sensor outputs requiring accurate amplification rather than high bandwidth. The single-amplifier configuration and external offset adjustment can simplify calibration around sensors such as resistive bridges or current-output transducers. Its approximately 0 to 70 C operating range covers commercial applications, but the exact input bias current, offset, and common-mode specifications are not provided in the verified snippets. Validate those parameters against the TI datasheet before choosing resistor values and supply rails.
推荐
Laboratory Measurement Equipment
OP07CDR is appropriate for general-purpose laboratory measurement circuits that amplify small differential signals and benefit from offset adjustment. Its 600 kHz gain-bandwidth product is sufficient for many moderate-speed measurement paths, and the 0.3 V/us slew rate helps preserve large-signal behavior compared with very slow precision amplifiers. For bench instruments, provide local supply bypassing and use a clean reference ground. The supplied data does not confirm rail-to-rail operation, so keep the signal inside the manufacturer-specified linear range.
推荐
Analog Feedback and Control Loops
The OP07CDR can support analog feedback networks, integrators, and control-loop elements where low offset and adjustable calibration are important. Its 600 kHz gain-bandwidth product and 0.3 V/us slew rate provide a practical operating range for moderate loop bandwidths, but stability depends on the exact noise gain, load, and compensation network. Start with the manufacturer's application guidance and verify output current, capacitive-load behavior, and saturation recovery before applying it to a new control topology.
推荐
Data Acquisition and Analog Filtering
OP07CDR is useful in data-acquisition channels that amplify or buffer sensor, transducer, or conditioning signals before digitization. The device is identified as a standard general-purpose amplifier with one circuit and a 600 kHz gain-bandwidth product, making it a reasonable choice for moderate-bandwidth analog paths. External offset adjustment can reduce channel calibration error, while the single SOIC package simplifies assembly. Confirm anti-aliasing-filter stability and output drive against the actual ADC input before production release.
推荐
Audio and Low-Level Analog Processing
OP07CDR can be evaluated for low-level audio or analog processing circuits where a clean, adjustable gain stage is more important than wide bandwidth. The low-offset architecture and external offset adjustment may help preserve signal integrity in quiet measurement paths, while the 0-to-70 C range targets commercial environments. Because the verified snippets do not provide complete noise, output-current, or common-mode data, verify those specifications before using it in high-gain audio stages or capacitive-load networks.

设计说明
Place the supply bypass capacitor immediately beside the OP07CDR supply pins and keep the return path short to the circuit ground reference. The verified operating range is approximately plus or minus 3 V to plus or minus 18 V, but the supplied data does not specify the recommended capacitor values or minimum load behavior. Use the manufacturer datasheet and reference circuit for final values, then verify startup and output settling on the actual load.
Route the high-impedance input, feedback, and offset-adjustment nets away from switching nodes, inductors, and digital clock traces. Keep feedback resistors close to the amplifier pins to minimize parasitic capacitance and susceptibility to PCB leakage. Because OP07CDR supports external offset adjustment, treat the adjustment network as a sensitive precision node and avoid long exposed traces where contamination or moisture can shift the calibration.
Do not assume rail-to-rail input or output operation from the general-purpose description. The supplied snippets do not verify the full input common-mode range, output swing, input bias current, or noise figures, so first confirm those limits in the TI datasheet for the selected supplies and load. Also verify the external offset-adjustment circuit values before copying a generic OP07C schematic.
合规信息
RoHS compliance is reported by the verified FindMyChip listing. The supplied data does not independently establish REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not indicated and is treated as not applicable for this commercial general-purpose amplifier.
