TS507CD - 1.9MHz Precision Rail-to-Rail Op Amp | STMicroelectronics
MPN： TS507CD ✓ 啟用中TS507CD 概覽
An operational amplifier is a voltage-feedback amplifier used to amplify, buffer, filter, or compare small analog signals. The TS507 belongs to the operational-amplifier hierarchy within analog ICs and broader semiconductor signal-conditioning systems. Its rail-to-rail input stage accepts signals close to the supply rails, while the rail-to-rail output stage provides useful output swing near both limits.
The TS507CD uses precision trimming to achieve low input-offset voltage without external zeroing. Its listed maximum input-offset voltage is 550 µV, and its typical common-mode rejection ratio is 115 dB. A 1.9 MHz gain-bandwidth product supports general-purpose closed-loop operation, while the low 850 µA supply current suits low-power analog systems.
The device is specified as a single general-purpose amplifier in an 8-SOIC package. Its operating temperature range is listed as 0°C to 85°C, and its typical output-current capability is 128 mA. These characteristics make it appropriate for precision sensor interfaces, active filters, signal buffers, and portable equipment where low offset and low supply current are more important than high bandwidth.
Typical uses include bridge-sensor amplification, transducer-signal conditioning, low-frequency active filters, and buffered analog measurements. Because the amplifier operates rail-to-rail at the input and output, system designers can use more of the available supply range, but common-mode and output-swing limits still require verification under the intended load and supply conditions.
When laying out a TS507CD circuit, keep feedback components and the input source connections short, and route high-impedance inputs away from switching nodes. Decoupling capacitors should be placed close to the supply and ground pins. Confirm gain-bandwidth, output-swing, and stability requirements against the actual gain, load, supply voltage, and operating temperature.
This page combines the TS507CD device description, package information, application guidance, comparison parameters, and verified sourcing references to help engineers evaluate the amplifier and identify technically suitable alternatives before PCB release.

典型應用
TS507CD 適用於 6 應用s: Precision Sensor Signal Conditioning, Low-Frequency Active Filters, Battery-Powered Instrumentation, Analog Buffering, Threshold and Comparison Circuits, Industrial Process Measurement.
Precision Sensor Signal Conditioning
The TS507CD is well suited to conditioning low-level sensor outputs because its input-offset voltage is specified at no more than 550 µV and its common-mode rejection ratio reaches 115 dB typical. It can amplify a bridge, resistive sensor, or low-level transducer signal while the rail-to-rail input stage accommodates signals near either supply rail. According to the STMicroelectronics datasheet, internal trimming avoids external offset-zeroing components, reducing calibration overhead. Place the amplifier close to the sensor, keep high-impedance inputs short, and verify input bias-current error against the sensor source impedance.
推薦
Low-Frequency Active Filters
The TS507CD can implement low-frequency active filters because its 1.9 MHz gain-bandwidth product provides useful open-loop bandwidth for precision filter stages. Its 850 µA typical supply current also reduces the penalty when several amplifier sections operate from a compact analog supply. Rail-to-rail input and output behavior can increase signal range within the supply envelope. According to the STMicroelectronics datasheet, the TS507 maintains stable characteristics over its supply range. Select resistor values for the intended gain and frequency, then verify phase margin, output swing, and noise at each practical operating point.
推薦
Battery-Powered Instrumentation
The TS507CD fits portable measurement systems where amplifier power must remain modest without sacrificing DC precision. Its supply current is 850 µA typical, while the 550 µV maximum input offset and 115 dB typical CMRR help preserve measurement accuracy in low-level analog channels. Rail-to-rail operation allows useful signal handling when the system operates near its supply limits. According to the STMicroelectronics datasheet, the device is a high-performance precision amplifier with internally trimmed offset. Account for resistor divider currents, sensor leakage, regulator quiescent current, and output-load demand in the complete battery budget.
推薦
Analog Buffering
The TS507CD can buffer high-impedance sources before feeding a sampling or processing stage. A voltage follower takes advantage of the amplifier’s low offset voltage and high common-mode rejection while avoiding loading of the source. The 1.9 MHz gain-bandwidth product provides ample bandwidth for many slow industrial and instrumentation signals. According to the STMicroelectronics datasheet, the rail-to-rail input stage accepts signals near the supply limits. Confirm the source impedance, capacitive loading, output-current demand, and stability behavior; adding a small isolation resistor at the output can help isolate downstream capacitance.
推薦
Threshold and Comparison Circuits
The TS507CD supports precision threshold detection when a low-level signal must be compared against a reference. Its maximum input-offset voltage of 550 µV limits the input-referred threshold error, and the 115 dB typical CMRR reduces output movement as common-mode voltage changes. The rail-to-rail output stage can produce useful logic-level transitions when supply and loading conditions are appropriate. According to the STMicroelectronics datasheet, the device is intended for stable general-purpose precision amplification. Check output saturation, input range, noise around the threshold, and propagation behavior for the specific comparator configuration.
推薦
Industrial Process Measurement
The TS507CD is suitable for process-measurement channels that combine moderate bandwidth with low DC error. The 1.9 MHz gain-bandwidth product supports many sensor and actuator signals, while rail-to-rail input operation is useful when the source voltage approaches a supply rail. Its 850 µA typical supply current is modest for continuously powered equipment. According to the STMicroelectronics datasheet, the TS507 provides very low offset through internal trimming. For industrial deployment, verify the exact operating-temperature grade, transient immunity, isolation requirements, and stable reference components around the measurement chain.

主要差異化特點
- Precision offset performance with internal trimming (對比General-purpose 8-SOIC operational amplifiers)

- Low supply demand for portable analog channels (對比TS507ID)
設計說明
Place the TS507CD close to the signal source and keep the inverting feedback loop compact. High-impedance input and feedback nodes should have short traces and minimal parasitic capacitance because they can pick up interference and affect noise gain. Route away from switching nodes and motor-control return currents. Follow the manufacturer datasheet pin-configuration diagram during layout and keep ground returns continuous beneath the analog circuitry.
Use the decoupling network and component placement specified in the manufacturer datasheet, placing the required capacitor directly between the supply and ground pins. A short, low-inductance path is more effective than a distant capacitor because the lead and board inductance can dominate at higher frequencies. Keep analog and digital return currents separated where possible, and use a continuous ground plane with careful routing beneath sensitive amplifier inputs.
Do not assume that rail-to-rail input and output operation permits output voltages exactly at the supply rails under every load. Verify output swing, output-current capability, and stable operation with the actual supply voltage and load. Also account for input bias-current error, resistor tolerances, and the 550 µV maximum offset voltage. These checks are particularly important when the source impedance is high or the measured signal is small.
For capacitive loads, start with a small isolation resistor between the amplifier output and the load if the application permits. Confirm stability with the intended gain, load, supply, and temperature rather than relying only on nominal gain-bandwidth product. The 1.9 MHz bandwidth is sufficient for many low-frequency measurement circuits, but high noise gain or heavy capacitive loading can reduce usable bandwidth and phase margin.
