Product details
Overview
TS507IYLT from STMicroelectronics is a high-precision rail-to-rail input/output operational amplifier optimized for automotive and industrial signal conditioning. It delivers 25 µV typical input offset voltage, 1.9 MHz gain bandwidth, 45° phase margin with 100 pF load, 0.8 mA supply current at 2.7 V, and operates from 2.7 V to 5.5 V - enabling accurate low-voltage sensing in battery-powered medical instrumentation.
For engineers reviewing the TS507IYLT datasheet, TS507IYLT pinout, TS507IYLT application, or TS507IYLT equivalent, key selection criteria include ultra-low offset drift (1 µV/°C), rail-to-rail output swing into 600 Ω, latchup immunity, and AEC-Q100 qualification for harsh-environment deployment.
Technical Context
The TS507 employs proprietary trimming to achieve 25 µV typ offset without external zeroing, maintaining stability across 2.7–5.5 V supply and –40°C to +125°C operation. Its internal architecture supports rail-to-rail input common-mode range (VDD to VCC) and delivers 131 dB large-signal voltage gain with 105 dB PSRR.
It features robust capacitive-load drive capability: 45° phase margin with 100 pF, validated via out-of-loop and in-the-loop compensation techniques (AN2653). ESD protection reaches 5 kV HBM, and latchup immunity meets Class A per JEDEC JESD78.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 25 µV typ (max 100 µV) - enables µV-level DC accuracy in precision sensor front-ends without calibration. |
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct integration into single-cell Li-ion (3.0–4.2 V) and 3.3 V/5 V system rails. |
| Gain Bandwidth Product | 1.9 MHz - sufficient for anti-aliasing filters, active RC stages, and medium-speed transducer amplification. |
| Phase Margin | 45° with 100 pF load - ensures stable unity-gain follower operation driving ADC input capacitance or long traces. |
| Supply Current | 0.8 mA at 2.7 V - allows continuous operation in portable devices with multi-year battery life (e.g., handheld diagnostics). |
| Output Drive | ±70 mA min sink/source at 2.7 V - drives 600 Ω loads while maintaining rail-to-rail swing, critical for driving SAR ADC references. |
| PSRR / CMRR | 105 dB PSRR, 115 dB CMRR - rejects power-supply ripple and common-mode noise in noisy automotive environments. |
Pinout & Package
SOT23-5 micropackage (2.8 mm × 2.9 mm footprint); thermally enhanced for high-density PCB layouts in space-constrained modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Negative supply rail | Connects to ground or negative reference; enables true rail-to-rail input common-mode range down to VDD. |
| 2 - IN+ | Non-inverting input | High-impedance node (8 nA max bias current) for precision voltage sensing or buffer configuration. |
| 3 - IN− | Inverting input | Differential input terminal; used in closed-loop configurations (e.g., instrumentation amp front-end). |
| 4 - OUT | Amplifier output | Rail-to-rail capable output delivering ±70 mA into 600 Ω while maintaining <125 mV saturation drop. |
| 5 - VCC | Positive supply rail | Accepts 2.7–5.5 V; PSRR of 105 dB minimizes sensitivity to supply noise in mixed-signal systems. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low offset voltage | 25 µV typ (100 µV max) - eliminates need for manual nulling in medical-grade analog front-ends. |
| Rail-to-rail I/O | VIN = VDD to VCC, VOUT = VDD to VCC - maximizes dynamic range in low-voltage battery systems (e.g., 3.3 V IoT sensors). |
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to +125°C) - certified for engine control, body electronics, and ADAS sensor interfaces. |
| High ESD robustness | 5 kV HBM - withstands handling and board-level ESD events without parameter shift or failure. |
| Latchup immunity | Class A per JEDEC JESD78 - prevents destructive latchup during overvoltage transients in industrial PLC inputs. |
Applications
| Medical Patient Monitor Front-End | Automotive Cabin Temperature Sensor |

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; not AEC-Q100 qualified. | Better for ultra-low-offset DC apps (e.g., strain gauge bridges), unsuitable for >100 kHz signal paths or automotive use. | Select when µV-level offset dominates over speed and qualification requirements. |
| MCP6V81T-E/OT | Zero-drift architecture (0.01 µV/°C drift), 1.8 MHz GBW, but 1.6 mA supply current and no AEC-Q100 rating. | Superior long-term stability for lab equipment; higher quiescent current limits battery life in portable designs. | Prefer for metrology-grade instruments where drift dominates over power and automotive compliance. |
Compared with OPA333AIDBVR and MCP6V81T-E/OT, TS507IYLT uniquely balances ultra-low offset (25 µV typ), automotive qualification, and 1.9 MHz bandwidth at sub-1 mA supply - making it optimal for cost-sensitive, safety-critical embedded systems requiring both precision and ruggedness.

FAQ
What is the maximum capacitive load the TS507IYLT can drive stably in unity-gain configuration?
The TS507IYLT maintains 45° phase margin with up to 100 pF capacitive load in unity-gain follower configuration at 25°C. For larger loads (e.g., 300–550 pF), ST Application Note AN2653 recommends out-of-loop (series ROL) or in-the-loop (RC feedback) compensation to preserve stability without sacrificing bandwidth.
Does TS507IYLT support dual-supply operation?
No - TS507IYLT is designed for single-supply operation with VDD referenced to ground (0 V) and VCC ranging from 2.7 V to 5.5 V. Its rail-to-rail input extends from VDD to VCC, enabling true single-supply functionality without split-rail generation.
How does the TS507IYLT's offset voltage perform over temperature?
Input offset voltage drift is specified at 1 µV/°C over the full operating range (–40°C to +125°C). At 25°C, typical Vio is 25 µV; worst-case over temperature is 400 µV for TS507I grade - verified by statistical distribution testing per Figure 1 and Figure 4 in the datasheet.
Is the SOT23-5 package of TS507IYLT RoHS and REACH compliant?
Yes - TS507IYLT is manufactured in full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The SOT23-5 package uses lead-free matte tin plating and halogen-free molding compound, with full material declarations available via ST's ECOPACK® documentation.
