TS507ID - Low-Offset Rail-to-Rail Op Amp | STMicroelectronics
料号： TS507ID ✓ 量产中TS507ID 概述
A rail-to-rail operational amplifier is an amplifier whose input common-mode range and output swing extend close to both supply-voltage limits. This capability is valuable when the signal being amplified operates near a positive or negative rail and a conventional amplifier would saturate. The TS507 therefore suits precision instrumentation, sensor interfaces, low-level signal conditioning, and measurement systems where usable signal range is more important than absolute isolation from the rails.
The TS507ID is identified by DigiKey and Mouser as a standard, general-purpose instrumentation amplifier section in an 8-SOIC package. Its trimmed internal design targets stable electrical characteristics across the operating range and very low offset without external adjustment. For designs requiring tighter control of input bias current, offset drift, noise, bandwidth, supply current, or temperature range, consult the manufacturer datasheet and select the appropriate TS507 grade and package variant.
Because the TS507ID accepts both positive and negative signal inputs and supports near-rail output swing, it can serve as the active element in difference amplifiers, current-to-voltage converters, bridge-sensor front ends, and precision feedback networks. The 8-pin SOIC footprint also allows it to be placed in the same general layout class as many standard single op amps, although engineers should verify the actual pin assignment and stability requirements before substituting another device.
When designing with the TS507ID, begin by defining the signal amplitude, common-mode range, required output swing, source impedance, and noise gain. Check the datasheet for the operating voltage range, unity-gain bandwidth, slew rate, input bias current, offset voltage, noise density, and stability conditions. Place the feedback components close to the amplifier, keep sensitive input nodes away from switching-current paths, and use a ground layout that minimizes voltage drops across analog return currents.
This page combines manufacturer-level product information, verified distributor listings, package and pin-assignment guidance, application analysis, and drop-in replacement guidance. It also distinguishes confirmed package-compatible TS507 family variants from options that require additional electrical verification, helping engineers narrow a redesign quickly before committing a new component to a PCB.

典型应用
TS507ID 适用于 6 应用s: Precision Sensor Signal Conditioning, Shunt-Based Current Measurement, Precision Bridge-Sensor Front End, Battery-Powered Analog Monitoring, Instrumentation and Data-Acquisition Front End, Low-Level Audio and Communication Amplification.
Precision Sensor Signal Conditioning
The TS507ID is appropriate for conditioning low-level sensor outputs because it combines rail-to-rail input capability with a very low internally trimmed offset voltage. In a noninverting or differential front end, this allows the useful signal range to extend close to the supply rails and reduces the fixed error introduced by amplifier offset without an external null adjustment. The stage remains well suited to resistive sensors, conditioned transducer outputs, and low-voltage monitoring signals. Verify the input common-mode limits, bias current, noise gain, and stability at the intended supply voltage before layout release.
推荐
Shunt-Based Current Measurement
The TS507ID can amplify the differential voltage developed across a shunt resistor for power monitoring, battery analysis, or laboratory instrumentation. Rail-to-rail input and output operation preserves more of the small sense voltage than a conventional amplifier that cannot approach the rails, while low offset supports accurate measurements near zero current. Keep the sense-resistor and amplifier layout compact to avoid converting current into additional error voltage. Confirm input bias current, common-mode range, and thermal behavior of the shunt during design verification.
推荐
Precision Bridge-Sensor Front End
A bridge sensor produces a small differential signal around a common-mode voltage, and the TS507ID can form the amplifier element of a precision difference stage. Its internally trimmed low offset reduces the need for manual calibration, while rail-to-rail input capability provides flexibility when the bridge excitation and signal range are constrained by the supply voltage. Resistor-network matching remains a major source of error in such designs. Select gain and common-mode limits with margin, and evaluate the amplifier's bias-current effect on the high-impedance bridge nodes.
推荐
Battery-Powered Analog Monitoring
The TS507ID is useful in low-voltage instrumentation where the monitored signal may occupy much of the available supply range. Rail-to-rail input operation reduces the risk of input saturation near the positive rail, and rail-to-rail output capability maximizes the usable logic or measurement swing. The trimmed offset supports repeatable readings without external zeroing hardware. Because the exact supply-current and temperature limits must be checked for the ordered TS507ID grade, confirm the operating range and quiescent current in the datasheet before selecting it for a battery design.
推荐
Instrumentation and Data-Acquisition Front End
The TS507ID can serve as the input amplifier in laboratory instrumentation and data-acquisition equipment where a compact 8-pin SOIC implementation and low offset are valuable. Rail-to-rail operation permits measurement of bipolar or unipolar signals that approach the supply limit, while the single-amplifier format simplifies analog routing around the IC. Place the amplifier close to the source connector to limit noise pickup, and route high-impedance inputs away from digital and switching paths. Confirm bandwidth and slew-rate requirements against the intended gain.
推荐
Low-Level Audio and Communication Amplification
The TS507ID can amplify low-level analog signals in audio or communication equipment when very low offset and near-rail signal handling are important. Its single-amplifier SOIC package allows implementation as a preamplifier, active filter element, or gain stage without excessive board area. Offset reduction improves waveform symmetry at low signal levels, but system noise, distortion, and stability depend on the selected gain, load, and feedback network. Review the manufacturer noise, bandwidth, slew-rate, and output-drive curves before using the device in high-fidelity audio paths.

设计说明
Place the TS507ID close to the signal source and connect the feedback network with short, direct traces. High-impedance input and inverting nodes should remain away from switching nodes, inductors, relay contacts, and digital return currents. Keep the analog ground return compact and use the package pin assignment in the manufacturer datasheet to plan the ground connection. These layout practices reduce parasitic capacitance, leakage coupling, and ground-induced error that can dominate a low-offset precision amplifier.
Do not assume that every 8-pin single op amp is pin-compatible with the TS507ID. Rail-to-rail capability does not guarantee identical pin functions, input bias current, output drive, or stability. Before a substitution, compare the complete pin-description table, supply range, common-mode range, offset, bandwidth, slew rate, load capability, and recommended feedback values. For gain configurations where the device becomes unstable, follow the manufacturer guidance for noise gain and output isolation rather than changing only the external resistor values.
Evaluate the complete signal chain, including source impedance, gain, sensor or shunt output impedance, and cable capacitance, before fixing the bandwidth target. Very low offset improves measurement accuracy but does not remove noise or drift contributed by the source and external resistor network. Use matched, stable resistors for precision difference and gain stages, and verify the amplifier's noise-gain stability with the final load. Where the source is remote or high impedance, add appropriate guarding or shielding and keep the input route short.
