Product details
Overview
TS507ILT 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 product, and operates from 2.7 V to 5.5 V supply - enabling accurate signal conditioning in battery-powered medical instrumentation and portable devices.
For engineers reviewing the TS507ILT datasheet, TS507ILT pinout, TS507ILT application, or TS507ILT equivalent, key selection criteria include ultra-low offset drift (1 µV/°C), rail-to-rail output swing with <120 mV drop at 600 Ω load, 45° phase margin into 100 pF, and automotive-grade temperature range (–40 °C to +125 °C) per AEC-Q100 qualification.
Technical Context
The TS507ILT uses proprietary trimming to achieve 25 µV typ offset without external nulling, maintaining stability across its full 2.7–5.5 V supply range. Its internal architecture ensures consistent CMRR (≥91 dB) and PSRR (≥89 dB) over temperature and common-mode voltage (0 V to VCC).
It supports stable unity-gain operation with ≥45° phase margin into 100 pF capacitive loads and delivers 0.6 V/µs slew rate while consuming only 0.8 mA at 2.7 V - making it suitable for precision DC-coupled amplification and sensor front-ends where power and accuracy are co-constrained.
Key Specifications

Pinout & Package
TS507ILT is housed in a space-saving SOT23-5 micropackage (2.8 mm × 2.9 mm footprint), optimized for high-density PCB layouts in portable and automotive electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Positive supply rail | Connects to main system supply (2.7–5.5 V); decoupling capacitor required near pin for stability. |
| 2 - IN+ | Non-inverting input | High-impedance node (IIB = 6–8 nA typ); accepts rail-to-rail common-mode voltage (0 V to VCC). |
| 3 - IN− | Inverting input | Differential input terminal; matched to IN+ for low offset and high CMRR (≥91 dB). |
| 4 - OUT | Amplifier output | Rail-to-rail capable; sinks/sources ≥35 mA at 2.7 V and maintains <120 mV headroom at 600 Ω load. |
| 5 - VCC | Negative supply rail / ground reference | Typically connected to system GND; supports single-supply operation with true 0 V input capability. |
Key Features
| Feature | Design Value |

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 higher quiescent current (17 µA vs. 800 µA) and no AEC-Q100 rating. | Preferred for ultra-low-offset lab equipment; unsuitable for automotive or extended-temp industrial use. | Select when offset is primary constraint and temperature range ≤85 °C suffices. |
| MCP6V81T-E/OT | Zero-drift architecture (0.01 µV/°C drift), but lower GBP (1 MHz) and no specified 100 pF phase margin. | Better for DC-stable integrators; less suited for AC-coupled sensor buffers requiring >1 MHz bandwidth. | Select for sub-ppm/°C drift-critical applications where bandwidth ≤500 kHz is acceptable. |
Compared with OPA333AIDBVR and MCP6V81T-E/OT, TS507ILT uniquely balances automotive qualification, 1.9 MHz bandwidth, and 25 µV offset in a 5-pin SOT23 - offering optimal trade-off for cost-sensitive, high-reliability portable and automotive signal chains.

FAQ
What is the maximum capacitive load the TS507ILT can drive while maintaining stability?
The TS507ILT guarantees ≥45° phase margin with a 100 pF capacitive load in unity-gain configuration, as verified in the datasheet (Figure 20). For larger loads (e.g., 300–550 pF), external compensation (e.g., out-of-the-loop resistor ROL) is recommended per Application Note AN2653 - enabling stable operation without oscillation or excessive settling time.
Does the TS507ILT support true single-supply operation down to 0 V input?
Yes. The TS507ILT features rail-to-rail input with common-mode voltage range extending from VCC (typically GND) to VDD, allowing direct interfacing with 0 V-referenced sensors such as thermistors or bridge outputs. Input bias current remains stable (6–8 nA typ) across this full range, preserving accuracy in DC-coupled designs.
How does the TS507ILT's offset voltage perform over temperature?
TS507ILT exhibits a maximum input offset drift of 1 µV/°C across its full operating range (–40 °C to +125 °C), as confirmed in Tables 3–5. This low drift - combined with 25 µV typ initial offset - ensures total error remains below ±200 µV over automotive temperature extremes, eliminating need for periodic recalibration in field-deployed systems.
Is the SOT23-5 package of TS507ILT compatible with standard reflow profiles?
Yes. The TS507ILT in SOT23-5 (package code: M5) is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C. Its thermal resistance (RthJA = 250 °C/W) and small footprint (2.8 mm × 2.9 mm) allow reliable soldering on dense PCBs without thermal stress-induced parametric shift or delamination.
