Product details
Overview
TS507IDT from STMicroelectronics is a high-precision rail-to-rail input/output operational amplifier optimized for low-voltage, low-power systems. It delivers 25 µV typical input offset voltage, 1.9 MHz gain bandwidth, 45° phase margin with 100 pF load, and operates from 2.7 V to 5.5 V - enabling accurate signal conditioning in battery-powered medical sensors and portable instrumentation.
For engineers reviewing the TS507IDT datasheet, TS507IDT pinout, TS507IDT application, or TS507IDT equivalent, this page provides verified pin functions, automotive-grade performance specifications, real-world stability behavior with capacitive loads, and validated alternatives for precision analog front-ends requiring ultra-low drift and rail-to-rail swing.
Technical Context
The TS507IDT employs proprietary trimming to achieve 25 µV typ (100 µV max) input offset without external nulling. Its internal architecture maintains stable DC performance across 2.7–5.5 V supply and −40 °C to +125 °C temperature range, with CMRR ≥91 dB and PSRR ≥89 dB.
It supports stable unity-gain operation with up to 100 pF capacitive load (45° phase margin), features 0.6 V/µs slew rate, 12 nV/√Hz input voltage noise, and latchup immunity per Class A - making it suitable for closed-loop sensor interfaces where output fidelity and thermal robustness are critical.
Key Specifications

Pinout & Package
TS507IDT is housed in a space-saving SOT23-5 micropackage (2.8 mm × 2.9 mm footprint), qualified for automotive applications and optimized for high-density PCB layouts in portable devices.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 - IN+ | Non-inverting input | High-impedance node (Iib = 6–160 nA); accepts rail-to-rail common-mode voltage (VDD to VCC). |
| 3 - IN− | Inverting input | Differential input terminal; matched to IN+ for <1 µV/°C drift and minimal CMRR degradation. |
| 4 - OUT | Amplifier output | Rail-to-rail capable (VOH ≤ 125 mV, VOL ≤ 125 mV @ 600 Ω); drives 10 kΩ loads directly. |
| 5 - VCC | Negative supply rail / ground reference | Typically connected to system GND; supports true single-supply operation with VCC = 0 V. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Lower offset (10 µV max), but only 350 kHz GBW and 0.16 V/µs slew rate. | Better for ultra-low-offset DC-coupled sensors; unsuitable for >50 kHz signal paths or fast settling. | Choose when offset dominates performance budget and bandwidth <100 kHz suffices. |
| MCP6V81T-E/OT | Higher quiescent current (1.2 mA vs. 0.79 mA), wider offset range (25–200 µV), no AEC-Q100 rating. | Lacks automotive qualification and thermal stability; better suited for commercial-grade consumer electronics. | Prefer for cost-sensitive non-automotive designs where AEC-Q100 is not mandated. |
Compared with OPA333AIDBVR and MCP6V81T-E/OT, TS507IDT uniquely balances ultra-low offset, 1.9 MHz bandwidth, automotive qualification, and sub-1 mA supply current - making it the optimal choice for battery-powered medical and automotive sensor front-ends demanding both precision and speed.

FAQ
What is the maximum capacitive load the TS507IDT can drive while maintaining stability?
The TS507IDT maintains 45° phase margin with up to 100 pF capacitive load in unity-gain configuration, as verified in the official datasheet (Figure 20). For larger loads, external compensation (e.g., out-of-the-loop resistor) is required - application note AN2653 provides design abacuses for selecting ROL values based on target phase margin and CL.
Does TS507IDT support true single-supply operation down to 2.7 V?
Yes. TS507IDT operates from 2.7 V to 5.5 V with rail-to-rail input and output swing referenced to VCC = 0 V. Its input common-mode range extends from VDD to VCC, and output swings within 125 mV of either rail under 600 Ω load - enabling full-scale signal capture in 3.3 V microcontroller-based systems without level-shifting.
Is TS507IDT pin-compatible with other SOT23-5 op-amps like TS912IDT?
No. TS507IDT uses a non-standard pinout: Pin 1 = VDD, Pin 2 = IN+, Pin 3 = IN−, Pin 4 = OUT, Pin 5 = VCC. TS912IDT follows industry-standard SOT23-5 layout (Pin 1 = OUT, Pin 2 = −IN, Pin 3 = +IN, Pin 4 = V−, Pin 5 = V+), so direct replacement requires PCB redesign.
How does TS507IDT perform in terms of input bias current over temperature?
Input bias current is specified as 6 nA typ at 25 °C (2.7 V supply), rising to 160 nA max over full temperature range (−40 °C to +125 °C). This low, well-characterized Iib enables high-impedance sensor interfacing (e.g., pH electrodes or piezoresistive bridges) without significant offset shift due to bias current × source resistance.
