Product details
Overview
TS507CD from STMicroelectronics is a high-precision rail-to-rail input/output operational amplifier optimized for low-voltage, battery-powered systems. It delivers 25 µV typical input offset voltage, 1.9 MHz gain bandwidth, and rail-to-rail swing from 2.7 V to 5.5 V supply - enabling accurate signal conditioning in portable medical instrumentation and automotive sensor interfaces.
For engineers reviewing the TS507CD datasheet, TS507CD pinout, TS507CD application, or TS507CD 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 space-constrained designs.
Technical Context
The TS507CD 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 accuracy in DC-coupled sensor amplification without calibration. |
| Gain Bandwidth Product | 1.9 MHz - supports stable amplification of signals up to ~150 kHz in unity-gain buffer applications. |
| Supply Voltage Range | 2.7 V to 5.5 V - compatible with Li-ion, Li-poly, and 3.3 V/5 V system rails without level-shifting. |
| Phase Margin | 45° with 100 pF load - ensures stable operation driving capacitive loads like ADC input filters or long PCB traces. |
| PSRR | 105 dB - suppresses supply ripple to < 0.0003% of output error, critical for precision measurement circuits. |
| ESD Rating (HBM) | 5 kV - provides robust handling during board assembly and field operation in industrial environments. |
| Operating Temperature | 0 °C to +85 °C (TS507C grade) - qualified for commercial and extended-temperature embedded applications. |
Pinout & Package
The TS507CD is housed in a 5-pin 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 | 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 bias current) accepting signals from VDD to VCC; supports direct sensor interfacing. |
| 3 - IN− | Inverting input | Differential input terminal used for feedback configuration; matched to IN+ for minimal offset contribution. |
| 4 - OUTPUT | Amplified output | Rail-to-rail capable (±120 mV drop at 600 Ω load); drives ADC inputs, filters, or downstream analog stages directly. |
| 5 - VCC | Positive supply rail | Accepts 2.7–5.5 V; internal regulation ensures stable biasing across supply variation and temperature. |
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 paths. |
| Rail-to-rail I/O | Input range: VDD to VCC; Output swing: within 120 mV of rails - maximizes dynamic range in single-supply 3.3 V systems. |
| Stable with capacitive loads | 45° phase margin @ 100 pF - allows direct connection to ADC input capacitors or long traces without external compensation. |
| Low quiescent current | 0.8 mA at 2.7 V - extends battery life in always-on medical wearables and IoT sensor nodes. |
| Automotive qualification | AEC-Q100 stress-tested - validated for under-hood and cabin electronics where reliability and thermal robustness are mandatory. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture (0.02 µV/°C drift vs. TS507CD's 1 µV/°C); higher 350 kHz GBW but lower 1.8 V min supply. | Better for ultra-stable DC measurements below 100 Hz; less suitable for 2.7 V battery start-up or fast settling. | Select OPA333 when sub-µV/°C drift dominates design requirements and supply ≥ 1.8 V is guaranteed. |
| MCP6V81T-E/OT | Chopper-stabilized (0.25 µV max offset); 1.8 MHz GBW; higher 1.2 mA ICC at 3.3 V vs. TS507CD's 0.81 mA. | Superior low-frequency noise performance but higher power draw limits use in multi-day battery operation. | Choose MCP6V81 for lowest 1/f noise in sensor interfaces where average current > 1 mA is acceptable. |
Compared with OPA333AIDBVR and MCP6V81T-E/OT, the TS507CD offers the best balance of ultra-low offset (25 µV), low quiescent current (0.8 mA), and proven stability with capacitive loads - making it optimal for cost-sensitive, battery-powered precision analog systems requiring no external trimming.

FAQ
What is the maximum capacitive load the TS507CD can drive without oscillation?
The TS507CD maintains 45° phase margin with up to 100 pF capacitive load in unity-gain configuration, as verified in the datasheet (Figure 20). For loads >100 pF, external compensation (e.g., out-of-the-loop resistor per AN2653) is required to ensure stability - no internal compensation is provided.
Does the TS507CD support dual-supply operation?
Yes - the TS507CD operates with split supplies (e.g., ±2.5 V) as long as total VCC–VDD remains within 2.7 V to 5.5 V and absolute pin voltages stay within absolute maximum ratings (e.g., VCC ≤ 6 V, Vin ≤ VDD+0.3 V). Its rail-to-rail input allows common-mode range from VDD to VCC in all configurations.
How does the TS507CD's offset voltage perform over temperature?
The TS507CD exhibits 1 µV/°C typical offset drift over its full operating range (0 °C to +85 °C). At 25 °C, offset is 25 µV typ (100 µV max); worst-case drift across temperature yields ≤250 µV max for the TS507C grade - confirmed in Table 3 under "full temperature range" conditions.
Is the SOT23-5 package of TS507CD RoHS and REACH compliant?
Yes - the TS507CD SOT23-5 package is fully RoHS-compliant (Pb-free, halogen-free) and REACH-conformant, as documented in STMicroelectronics' official material declarations (Doc ID: CD00245215). Lead finish is matte tin, and the device meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1).
