Product details
Overview
TS507CDT 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 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 sensors and portable instrumentation.
For engineers reviewing the TS507CDT datasheet, TS507CDT pinout, TS507CDT application, or TS507CDT 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 loads - critical for precision analog front-ends in automotive and industrial environments.
Technical Context
The TS507CDT employs proprietary trimming to achieve sub-100 µV max input offset without external nulling. Its internal architecture maintains >45° phase margin with 100 pF load and delivers 131 dB large-signal voltage gain across full temperature range.
It operates over 2.7–5.5 V supply while sustaining rail-to-rail input common-mode range (VDD to VCC) and output swing within 120 mV of rails at 600 Ω load - supporting single-supply configurations in space-constrained embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 25 µV typ / 100 µV max - enables DC-coupled sensor interfaces without calibration. |
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct Li-ion and 3.3 V system rail operation. |
| Gain-Bandwidth Product | 1.9 MHz - sufficient for anti-aliasing filters and medium-speed transducer amplification. |
| Phase Margin | 45° with 100 pF load - ensures stable closed-loop behavior driving capacitive cables or ADC inputs. |
| PSRR | 105 dB - rejects power rail noise in noisy mixed-signal PCBs. |
| ESD Rating | 5 kV HBM - withstands handling in automated assembly and field-replaceable modules. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive and industrial control applications. |
Pinout & Package
TS507CDT is housed in a 5-pin 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 | Negative supply rail (typically ground); enables true rail-to-rail input common-mode down to VDD. |
| 2 | Inverting Input (−) | Differential input node; accepts signals from VDD to VCC with minimal CMRR degradation. |
| 3 | Non-inverting Input (+) | Differential input node; supports biasing networks for sensor bridges or reference buffers. |
| 4 | Output | Rail-to-rail output stage capable of sourcing/sinking ≥70 mA at 25 °C into 600 Ω. |
| 5 | VCC | Positive supply rail; defines upper rail for both input common-mode and output swing. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low offset voltage | 25 µV typ ensures <0.1% error in 25 mV biomedical sensor outputs without trimming. |
| Rail-to-rail I/O | Full dynamic range utilization from 2.7 V supply - eliminates level-shifting in single-supply data acquisition. |
| Latchup immunity | Class A rating prevents destructive failure during power sequencing or transient overvoltage events. |
| Stable with capacitive loads | 45° phase margin at 100 pF allows direct connection to long traces or ADC input capacitance without oscillation. |
| Automotive qualification | AEC-Q100 Grade 1 compliance verified per datasheet Rev 6 - suitable for engine control and ADAS subsystems. |

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; 0.1 µV/°C offset drift vs. TS507CDT's 1 µV/°C; higher 350 kHz GBW. | Preferred for ultra-stable DC measurements (e.g., precision weigh scales); less suited for >1 MHz signal paths. | Select when sub-µV/°C drift dominates over bandwidth requirements. |
| MCP6V81T-E/OT | Chopper-stabilized; 3 µV max offset; 1.8 V to 5.5 V supply; 1.2 MHz GBW; higher 1.6 µV/°C drift. | Better for ultra-low-voltage (1.8 V) systems but lacks automotive temp range (−40 °C to +125 °C). | Choose for cost-sensitive consumer devices where extended temperature is not required. |
Compared with OPA333AIDBVR and MCP6V81T-E/OT, the TS507CDT uniquely balances 1.9 MHz bandwidth, 5 kV HBM ESD, latchup immunity, and AEC-Q100 Grade 1 qualification - making it the only option qualified for safety-critical automotive signal chains requiring both speed and robustness.

FAQ
What is the maximum capacitive load the TS507CDT can drive stably?
The TS507CDT maintains 45° phase margin with up to 100 pF capacitive load in unity-gain configuration, as verified in the datasheet (Figure 20). For larger loads (e.g., >200 pF), external compensation - such as out-of-the-loop series resistor (ROL) - is required per AN2653 to prevent peaking or oscillation.
Does the TS507CDT support dual-supply operation?
No - the TS507CDT is specified only for single-supply operation from 2.7 V to 5.5 V between VCC (positive) and VDD (negative/ground). Its rail-to-rail input common-mode range extends from VDD to VCC, eliminating need for split supplies in most sensor interface designs.
How does the TS507CDT's offset voltage perform over temperature?
Offset voltage drift is guaranteed at ≤1 µV/°C over −40 °C to +125 °C (Table 3–5). At 25 °C, typical Vio is 25 µV; worst-case over full temperature range is 400 µV for TS507I grade - validated by statistical distribution plots (Figures 1–4) and HTB/THB reliability testing.
Is the SOT23-5 package of TS507CDT RoHS and REACH compliant?
Yes - the TS507CDT SOT23-5 package meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed in ST's official product change notices and material declarations (DocID10958 Rev 6, Section 5 Ordering Information).
