Product details
Overview
TC75S55FU(TE85L,F) from Toshiba Electronic Devices & Storage Corporation is a CMOS single operational amplifier with built-in phase compensation, designed for ultra-low-power operation at supply voltages as low as ±0.9 V or 1.8 V. It delivers 10 µA typical supply current at 3 V, 70 dB open-loop gain, and 160 kHz unity-gain bandwidth, enabling use in battery-powered sensor signal conditioning and portable medical monitoring circuits.
For engineers reviewing the TC75S55FU(TE85L,F) datasheet, TC75S55FU(TE85L,F) pinout, TC75S55FU(TE85L,F) application, or TC75S55FU(TE85L,F) equivalent, key selection criteria include its rail-to-rail input common-mode range (0–2.1 V at 3 V), 0.08 V/µs slew rate, pA-level input bias current, and SSOP-5 package compatibility with space-constrained PCB layouts.
Technical Context
The TC75S55FU(TE85L,F) integrates a fully compensated CMOS op-amp core optimized for single-supply operation down to 1.8 V, eliminating external compensation components. Its input stage supports rail-to-rail common-mode voltage (0–2.1 V at VDD = 3 V) and exhibits 1 pA typical input bias current with 2 mV typical input offset voltage.
Output stage delivers 100–450 µA sink capability and 10–20 µA source current at 3 V, enabling direct interface with high-impedance loads or low-power comparators. AC performance includes 160 kHz unity-gain bandwidth and 70 dB CMRR/SVRR - stable across 1.8–7 V supply range without external feedback tuning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 to 7 V (single supply) or ±0.9 to ±3.5 V (dual supply) - enables direct integration into Li-ion, coin-cell, and industrial 3.3/5 V systems |
| Supply Current (IDD) | 10 µA typ. at 3 V - reduces quiescent power to <30 µW, critical for multi-year battery life in IoT endpoints |
| Input Offset Voltage (VIO) | 2 mV typ. - ensures ≤0.1% gain error in 100 mV full-scale sensor amplification without trimming |
| Unity-Gain Bandwidth (fT) | 160 kHz at 3 V - sufficient for DC–10 kHz biosignal amplification (ECG, pulse oximetry) with stable phase margin |
| Slew Rate (SR) | 0.08 V/µs - limits large-signal settling time to ~25 µs for 2 V step, compatible with slow analog multiplexing |
| Common-Mode Input Range | 0 to 2.1 V at VDD = 3 V - supports direct sensing of ground-referenced resistive bridges or thermistors |
| Open-Loop Gain (GV) | 70 dB typ. - provides ≥1000 V/V closed-loop precision for gain-setting resistors with ≤0.1% tolerance |
Pinout & Package
TC75S55FU(TE85L,F) uses the SSOP-5 (Small Outline Package, 5-pin) with 0.65 mm lead pitch, measuring 2.9 × 2.8 × 1.25 mm and weighing 0.006 g (typ.). This ultra-compact surface-mount package supports high-density layout in wearables and implantable-grade modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: IN(−) | Inverting input | Accepts feedback network connection; high-impedance (pA bias) enables high-R gain setting without drift |
| 2: VSS | Negative supply / GND | Reference node for single-supply operation; must be low-impedance to maintain PSRR >60 dB |
| 3: OUT | Amplifier output | Capable of sinking 450 µA while maintaining VOL ≤0.1 V - drives ADC reference buffers or LED bias directly |
| 4: IN(+) | Non-inverting input | Supports rail-to-rail common-mode range; used for sensor bridge mid-point or reference voltage sensing |
| 5: VDD | Positive supply | Accepts 1.8–7 V; internal regulation ensures stable biasing across voltage droop in battery discharge profiles |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 10 µA typical at 3 V - extends coin-cell lifetime beyond 10 years in always-on wake-up monitors |
| Built-in phase compensation | Eliminates need for external capacitor; guarantees stability with unity-gain follower configuration |
| pA-level input bias current | 1 pA typical - prevents voltage error in high-Z pH electrode or piezoelectric sensor interfaces |
| Rail-to-rail input common-mode range | 0 to VDD − 0.9 V at 3 V - enables direct amplification of signals referenced to system ground or VDD/2 |
| SSOP-5 compact footprint | 2.9 × 2.8 mm body - fits within 3 mm × 3 mm keep-out zones required by FDA-cleared wearable designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single CMOS op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-I/OT (Microchip) | Higher 100 µA IDD, 1 MHz fT, SOT-23-5 package; no dual-supply support | Better for higher-speed sensor sampling but increases battery load 10× vs. TC75S55FU(TE85L,F) | Select when bandwidth >100 kHz is required and supply current budget allows ≥100 µA |
| TSV911ICT (STMicroelectronics) | 25 µA IDD, 8 MHz fT, rail-to-rail I/O, same SSOP-5 footprint; requires external compensation for unity-gain stability | Superior speed and output drive, but adds design complexity and board area for compensation capacitor | Select when driving capacitive loads >100 pF or requiring faster settling than TC75S55FU(TE85L,F)'s 25 µs |
Compared with MCP6001T-I/OT and TSV911ICT, the TC75S55FU(TE85L,F) uniquely balances sub-10 µA supply current, guaranteed unity-gain stability, and SSOP-5 compactness - making it optimal for multi-year battery life in space-constrained analog front-ends where bandwidth ≤160 kHz suffices.

FAQ
What supply voltage ranges does the TC75S55FU(TE85L,F) support?
The TC75S55FU(TE85L,F) operates from a single supply of 1.8 to 7 V or dual supplies of ±0.9 to ±3.5 V. At 3 V, it draws only 10 µA typical supply current while maintaining 70 dB open-loop gain and 160 kHz unity-gain bandwidth - making TC75S55FU(TE85L,F) ideal for coin-cell and Li-ion-powered systems where voltage headroom is limited.
Does the TC75S55FU(TE85L,F) require external phase compensation components?
No. The TC75S55FU(TE85L,F) integrates internal phase compensation, enabling stable unity-gain follower operation without external capacitors. This simplifies PCB layout and eliminates tuning steps - a key differentiator versus uncompensated op-amps like TSV911ICT, where TC75S55FU(TE85L,F) offers plug-and-play stability in low-bandwidth sensor interfaces.
What is the input common-mode voltage range of the TC75S55FU(TE85L,F) at 3 V supply?
At VDD = 3 V, the TC75S55FU(TE85L,F) supports an input common-mode range of 0 to 2.1 V - covering the full ground-to-VDD/2 span. This allows direct interfacing with grounded resistive sensors (e.g., thermistors, strain gauges) without level-shifting circuitry, preserving accuracy and reducing bill-of-materials cost in TC75S55FU(TE85L,F)-based designs.
How does the TC75S55FU(TE85L,F) perform in terms of input bias current and offset voltage?
The TC75S55FU(TE85L,F) delivers 1 pA typical input bias current and 2 mV typical input offset voltage at 25°C. These values enable high-precision amplification of high-impedance sources such as pH electrodes or piezoelectric sensors - where even nanoamp-level leakage would corrupt signal integrity. TC75S55FU(TE85L,F) maintains these specs across its full operating temperature range (−40 to +85°C).
Is the TC75S55FU(TE85L,F) pin-compatible with other SSOP-5 op-amps?
The TC75S55FU(TE85L,F) uses standard SSOP-5 pinout (IN−, VSS, OUT, IN+, VDD), matching industry conventions. However, pin compatibility does not guarantee functional equivalence - e.g., MCP6001T-I/OT shares the footprint but draws 10× more current and lacks dual-supply capability. Always verify electrical specifications before substituting TC75S55FU(TE85L,F) in existing layouts.
