Product details
Overview
TS507CLT 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 rail-to-rail swing 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 TS507CLT datasheet, TS507CLT pinout, TS507CLT application, or TS507CLT equivalent, key selection criteria include ultra-low offset drift (1 µV/°C), latchup immunity, 5 kV HBM ESD rating, and stable operation with 100 pF capacitive load - critical for precision analog front-ends in automotive and industrial sensor interfaces.
Technical Context
The TS507CLT employs proprietary trimming to achieve 25 µV typ offset without external zeroing, maintaining stability across its full 2.7–5.5 V supply range. Its 45° phase margin with 100 pF load and 131 dB large-signal voltage gain support robust closed-loop performance in unity-gain and high-gain configurations.
It features rail-to-rail input common-mode range (VDD to VCC) and output swing, enabling full dynamic range utilization in single-supply systems. The device exhibits 105 dB PSRR and 115 dB CMRR at low Vicm, ensuring high immunity to supply and common-mode noise in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 25 µV typ (max 100 µV) - enables sub-mV error in 12-bit+ data acquisition without calibration |
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct integration into Li-ion (3.0–4.2 V) and 3.3 V logic systems |
| Gain-Bandwidth Product | 1.9 MHz - sufficient for anti-aliasing filters up to ~150 kHz and sensor signal amplification |
| Slew Rate | 0.6 V/µs - ensures faithful reproduction of 100 kHz full-scale sine waves with <1% distortion |
| PSRR / CMRR | 105 dB / 115 dB - rejects >99.999% of supply ripple and common-mode interference in noisy PCB layouts |
| ESD Rating (HBM) | 5 kV - exceeds IEC 61000-4-2 Level 4, reducing need for external protection in handheld designs |
| Operating Temperature | −40 °C to +125 °C (TS507I grade) - qualified for under-hood automotive and industrial control applications |
Pinout & Package
TS507CLT is housed in a space-saving SOT23-5 micropackage (2.8 mm × 2.9 mm footprint), optimized for high-density PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Positive supply rail | Connects to system VCC (2.7–5.5 V); internal ESD protection tied to this pin |
| 2 - IN+ | Non-inverting input | Rail-to-rail CMVR (VDD to VCC); supports direct sensing of ground-referenced signals |
| 3 - IN− | Inverting input | Differential input node; matched bias current minimizes offset in transimpedance configurations |
| 4 - OUT | Amplifier output | Rail-to-rail swing; capable of sourcing/sinking ≥70 mA at 5 V (enables direct LED/driver interface) |
| 5 - VCC | Negative supply rail / ground reference | Typically connected to GND (0 V); defines lower rail for rail-to-rail operation and common-mode range |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low offset voltage | 25 µV typ (100 µV max) - eliminates need for manual nulling or digital offset correction in precision measurement |
| Rail-to-rail I/O | Full input CMVR (VDD to VCC) and output swing to within 120 mV of rails - maximizes ADC dynamic range utilization |
| Stable with capacitive loads | 45° phase margin @ 100 pF - enables direct driving of long traces, cables, or ADC input capacitance without oscillation |
| Latchup immunity | Class A per JEDEC JESD78 - prevents destructive failure during overvoltage or hot-swap events |
| Automotive qualification | AEC-Q100 Grade 1 (−40 °C to +125 °C) - certified for engine control, body electronics, and ADAS sensor signal chains |

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 | Zero-drift architecture (0.02 µV/°C drift), but higher 17 µA IQ and 350 kHz GBP | Better for µV-level DC stability over temperature; less suitable for >100 kHz signal paths | Choose when long-term DC accuracy outweighs bandwidth and power constraints |
| MCP6V81-E/MS | Chopper-stabilized (0.25 µV offset), 1.8 MHz GBP, 1.6 mA IQ, SO-8 only | Superior offset spec but higher supply current and larger package limits portable use | Prefer for cost-sensitive industrial sensors where SOT23-5 size and 0.8 mA IQ are not mandatory |
Compared with OPA333AIDBVR and MCP6V81-E/MS, TS507CLT uniquely balances ultra-low offset (25 µV), low power (0.8 mA), compact SOT23-5 packaging, and 1.9 MHz bandwidth - making it optimal for space-constrained, battery-operated precision analog systems requiring wide temperature reliability.

FAQ
What is the maximum capacitive load the TS507CLT can drive without compensation?
The TS507CLT maintains 45° phase margin with up to 100 pF capacitive load in unity-gain configuration, as verified in the datasheet (Figure 20). Driving larger loads (e.g., >200 pF) requires external compensation - such as the out-of-the-loop resistor technique described in Application Note AN2653 - to prevent peaking or oscillation.
Does the TS507CLT support true single-supply operation with input down to ground?
Yes. The TS507CLT features rail-to-rail input common-mode range extending from VDD (typically GND) to VCC, allowing direct interfacing with ground-referenced sensors and transducers. Input voltage can be as low as 0 V with no phase reversal or increased bias current - confirmed across all operating temperatures and supply voltages (2.7–5.5 V).
How does the TS507CLT's offset voltage perform over temperature and process variation?
Offset voltage is guaranteed ≤100 µV at 25 °C and ≤400 µV over full temperature range (−40 °C to +125 °C) for the TS507I grade. Drift is tightly controlled at 1 µV/°C max, and post-HTB (1000 h at 125 °C) testing shows minimal shift - confirming long-term stability required for automotive and medical applications.
Can the TS507CLT replace legacy op-amps like LMV321 in existing designs?
Yes, with design validation. TS507CLT offers superior specs - 25 µV vs. LMV321's 1.5 mV offset, 1.9 MHz vs. 1 MHz GBP, and 5 kV vs. 2 kV HBM ESD - but shares identical SOT23-5 pinout and supply range. Layout changes are unnecessary; however, stability with capacitive loads should be rechecked due to higher bandwidth and different phase margin profile.
