Product details
Overview
TC75S51F,LF 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 ±0.75 V or 1.5 V. It delivers 60 µA typical supply current at 3 V, 70 dB open-loop gain, and 0.5 V/µs slew rate, enabling use in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TC75S51F,LF datasheet, TC75S51F,LF pinout, TC75S51F,LF application, or TC75S51F,LF equivalent, key selection criteria include its rail-to-rail input common-mode range (0–2.5 V at 3 V supply), 1 pA input bias current, and SSOP-5 package compatibility with space-constrained PCB layouts.
Technical Context
The TC75S51F,LF employs a fully CMOS input stage and internal frequency compensation to eliminate external components while maintaining stability across capacitive loads up to 100 pF. Its design targets low-voltage analog signal conditioning where power budget and board area are critical constraints.
It operates over −40°C to +85°C with guaranteed performance at 1.5 V and 3.0 V supply rails, supporting dual-supply (±0.75 to ±3.5 V) and single-supply (1.5 to 7 V) configurations. Input offset voltage remains ≤10 mV across temperature and supply variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Supply Current (Typ.) | 60 µA at VDD = 3 V - enables multi-year battery life in always-on sensing nodes |
| Input Bias Current | 1 pA - minimizes error in high-impedance sensor front-ends (e.g., pH electrodes, photodiodes) |
| Open-Loop Gain | 70 dB - sufficient for precision DC amplification with <0.1% gain error at 100× closed-loop gain |
| Slew Rate | 0.5 V/µs at VDD = 3 V - supports bandwidth up to ~80 kHz for small-signal step response |
| Input Offset Voltage | 2 mV (typ.), ≤10 mV (max) - ensures sub-mV accuracy in 12-bit ADC reference buffering |
| Common-Mode Input Range | 0 to 2.5 V at VDD = 3 V - allows direct interfacing with 0–3.3 V microcontroller ADC inputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-E/OT | Higher supply current (100 µA typ.), wider supply range (1.8–6 V), no dual-supply support | Better suited for 1.8 V MCU systems; lacks ±0.75 V capability | Select when operating exclusively above 1.8 V and higher drive strength is needed |
| LMV321IDBVR | Higher input offset (3 mV typ.), 125 µA supply current, rail-to-rail output only (not input) | Lower cost but reduced DC accuracy and input range - limits sensor interface flexibility | Choose for cost-sensitive, non-precision applications where full rail-to-rail input is not required |
Compared with MCP6001T-E/OT and LMV321IDBVR, the TC75S51F,LF uniquely supports true dual-supply operation down to ±0.75 V and delivers the lowest input bias current (1 pA) among the three, making it optimal for ultra-high-impedance, low-power analog front-ends.

FAQ
What is the maximum operating temperature range for TC75S51F,LF?
The TC75S51F,LF is rated for operation from −40°C to +85°C ambient temperature. This industrial-grade range ensures reliable performance in portable medical devices, factory-floor sensors, and outdoor smart home equipment. The device maintains specified electrical characteristics-including input offset voltage, gain, and supply current-across this full range, as validated in Toshiba's production test flow.
Does TC75S51F,LF support dual-supply operation?
Yes, TC75S51F,LF supports dual-supply operation from ±0.75 V to ±3.5 V. This capability enables symmetric biasing for AC-coupled sensor interfaces and precision instrumentation where ground-referenced signals are impractical. The device's input common-mode range extends to the rails under both single- and dual-supply configurations, preserving design flexibility.
What is the input offset voltage specification for TC75S51F,LF at 1.5 V supply?
At VDD = 1.5 V and Ta = 25°C, the TC75S51F,LF has a typical input offset voltage of 2 mV, with a maximum of 10 mV. This specification is confirmed in Toshiba's official datasheet Section 2 (DC Characteristics at 1.5 V). The value remains stable across temperature and load, supporting accurate DC amplification in low-voltage sensor signal chains.
Can TC75S51F,LF drive a 10 kΩ load directly?
Yes, TC75S51F,LF can drive a 10 kΩ load, though output swing will be reduced compared to high-impedance loads. At VDD = 3 V and RL = 10 kΩ, VOH drops to approximately 2.5 V and VOL rises to ~0.2 V per Toshiba's load curves. For full rail-to-rail output swing, keep RL ≥ 100 kΩ; for lower-impedance loads, verify output compliance in the target application using the provided VOL/VOH vs. Isink/Isource graphs.
Is TC75S51F,LF RoHS compliant?
Yes, TC75S51F,LF is RoHS compliant. Toshiba confirms compliance with Directive 2011/65/EU (RoHS 2) and subsequent amendments, including restrictions on lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE. Full material declarations and compliance documentation are available through Toshiba's official product portal and authorized distribution channels.
