Product details
Overview
TC75S63TU,LF from Toshiba is a single low-noise operational amplifier in a 5-pin SON package, designed for precision analog signal conditioning in space-constrained applications. It delivers 7.8 nV/√Hz input noise, 3.5 MHz unity-gain bandwidth, and 500 μA supply current at 3.3 V, enabling high-fidelity amplification in battery-powered sensor front-ends and portable medical devices.
For engineers reviewing the TC75S63TU,LF datasheet, TC75S63TU,LF pinout, TC75S63TU,LF application, or TC75S63TU,LF equivalent, key selection criteria include its rail-to-rail input common-mode range (0–2.4 V at 3.3 V), low-phase-delay performance (−2.5° at 2 kHz), and guaranteed operation from −40°C to +85°C with no voltage-follower restriction.
Technical Context
The TC75S63TU,LF employs a CMOS input stage optimized for ultra-low input bias current (1 pA typ.) and low input offset voltage (1 mV typ.), supporting high-impedance source interfacing without significant error. Its open-loop gain of 100 dB and CMRR/SVRR of 80 dB (typ.) ensure stable DC accuracy under varying supply and common-mode conditions.
This op-amp operates across a wide 2.2–5.5 V supply range and features internal compensation for unity-gain stability. The −2.5° phase delay at 2 kHz and 1.0 V/μs slew rate (at ±1.65 V dual supply) reflect its suitability for low-distortion AC-coupled amplification and active filtering below 100 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.2 V to 5.5 V - supports direct integration into 3.3 V and 5 V systems without level-shifting. |
| Input Noise Voltage | 7.8 nV/√Hz @ 1 kHz - enables high-resolution amplification of microvolt-level sensor signals. |
| Unity-Gain Bandwidth | 3.5 MHz - sufficient for anti-aliasing filters and audio-band signal conditioning up to ~100 kHz. |
| Supply Current | 500 μA typ. @ 3.3 V - allows continuous operation in always-on wearable and IoT node designs. |
| Common-Mode Input Range | 0 V to 2.4 V @ VDD = 3.3 V - accommodates ground-referenced sensors and single-supply transducer interfaces. |
| Phase Delay | −2.5° @ 2 kHz - preserves waveform fidelity in precision instrumentation and feedback control loops. |
| Output Drive Capability | ±4 mA - drives 100 kΩ loads with <0.1 V saturation and supports moderate-capacitive loads with margin. |
Pinout & Package
TC75S63TU,LF is housed in a 5-pin SON (Small Outline No-lead) package designated SON5-P-0202-0.65S, measuring 2.0 mm × 2.0 mm × 0.6 mm with 0.65 mm pitch and wettable flank terminals for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive Supply | Connects to main power rail (2.2–5.5 V); decoupling capacitor required within 2 mm for stability. |
| IN(−) | Inverting Input | Differential input node; high-impedance CMOS input (1 pA bias current) minimizes loading on source. |
| VSS | Negative Supply / Ground | Reference return path; must be low-impedance; not necessarily ground when used in dual-supply configurations. |
| OUT | Amplifier Output | Capable of sourcing/sinking ±4 mA; output swing limited to 0.1 V above VSS and 0.1 V below VDD. |
| IN(+) | Non-Inverting Input | High-impedance input; common-mode range extends to VSS and up to 2.4 V at 3.3 V supply. |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Noise | 7.8 nV/√Hz enables accurate amplification of low-amplitude signals from piezoelectric sensors and thermopiles. |
| Rail-to-Rail Input | Common-mode range from VSS to 2.4 V at 3.3 V supply allows direct interface with ground-referenced transducers. |
| Ultra-Low Supply Current | 500 μA typ. supports multi-year battery life in always-on environmental monitoring nodes. |
| Stable Phase Response | −2.5° phase delay at 2 kHz ensures minimal group delay distortion in active filter and signal reconstruction paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-E/OT | Higher input noise (17 nV/√Hz), lower GBW (1 MHz), but wider supply range (1.8–6.0 V) and lower cost. | Acceptable for non-critical sensor buffering where noise <15 nV/√Hz is tolerable. | Choose when budget constraints outweigh noise sensitivity and bandwidth requirements. |
| OPA333AIDBVR | Lower offset (2 μV max), zero-drift architecture, but higher quiescent current (17 μA) and larger 5-pin SOT-23 package. | Better for DC-critical applications like precision weight scales, but unsuitable for ultra-low-power battery use. | Choose when microvolt-level DC accuracy is mandatory and supply current >500 μA is acceptable. |
Compared with MCP6001T-E/OT and OPA333AIDBVR, the TC75S63TU,LF uniquely balances sub-10 nV/√Hz noise, 3.5 MHz bandwidth, and sub-1 mA supply current in a 2.0 × 2.0 mm SON package-making it optimal for compact, battery-powered analog front-ends where both AC fidelity and energy efficiency are critical.

FAQ
What is the maximum load capacitance the TC75S63TU,LF can drive without oscillation?
The TC75S63TU,LF datasheet warns that higher load capacitance increases oscillation risk, even within common-mode voltage limits. While no explicit maximum value is specified, design guidelines recommend limiting capacitive loads to ≤100 pF and adding a 10–100 Ω series resistor near the output for loads exceeding 50 pF. Stability testing with actual PCB layout parasitics is advised before final validation of the TC75S63TU,LF in high-capacitance applications.
Does the TC75S63TU,LF support dual-supply operation?
Yes, the TC75S63TU,LF supports dual-supply operation, as confirmed by AC characteristics tested at VDD = +1.65 V and VSS = −1.65 V. Its absolute maximum ratings specify ±6 V differential input voltage and symmetric supply capability. When operated with dual supplies, the common-mode input range remains referenced to the midpoint between VDD and VSS, and the TC75S63TU,LF maintains full functionality including 1.0 V/μs slew rate and low-noise performance.
Is the TC75S63TU,LF pin-compatible with other Toshiba op-amps in the same SON5 package?
No documented pin compatibility exists between the TC75S63TU,LF and other Toshiba SON5 op-amps such as TC75S58FU or TC75S59FU. Each part has distinct internal topology and pin assignments; the TC75S63TU,LF uses VDD–IN(−)–VSS–OUT–IN(+) configuration, while others may differ. PCB layout must be verified against the specific TC75S63TU,LF pinout-no assumptions about interchangeability should be made without cross-referencing official Toshiba package drawings.
What is the typical input offset voltage drift over temperature for the TC75S63TU,LF?
The TC75S63TU,LF datasheet does not specify input offset voltage drift (dVIO/dT) as a guaranteed parameter. Only room-temperature DC characteristics are provided, with input offset voltage listed as 1 mV (typ.) at Ta = 25°C. For applications requiring tight DC stability across −40°C to +85°C, system-level calibration or external trimming is recommended, as the TC75S63TU,LF is not characterized for drift behavior in its published specifications.
Can the TC75S63TU,LF be used in a voltage follower configuration?
No-the TC75S63TU,LF datasheet explicitly prohibits use in voltage follower circuits (Note 2, Operating Ratings). Doing so may cause voltage oscillation due to phase margin limitations under unity-gain, high-capacitive-load conditions. For buffer applications, a minimum noise gain ≥2 (e.g., non-inverting amplifier with Rf/Rg ≥ 1) is required to ensure stability. This restriction applies directly to the TC75S63TU,LF and must be observed in all designs.
