Toshiba Semiconductor and Storage TC75S51FUTE85LF

Overview

TC75S51FUTE85LF from Toshiba Electronic Devices & Storage Corporation is a CMOS single operational amplifier with built-in phase compensation, designed for low-voltage (1.5–7 V) and ultra-low quiescent current (60 µA typ. at 3 V) operation. It delivers rail-to-rail output swing (VOH = 2.9 V, VOL = 0.1 V at RL ≥ 100 kΩ), 70 dB open-loop gain, and 0.6 MHz unity-gain bandwidth - enabling precision signal conditioning in battery-powered sensor interfaces.

For engineers reviewing the TC75S51FUTE85LF datasheet, TC75S51FUTE85LF pinout, TC75S51FUTE85LF application, or TC75S51FUTE85LF equivalent, key selection criteria include its SSOP-5 package footprint, ±7 V differential input voltage rating, 1 pA input bias current, and guaranteed operation from −40°C to +85°C across supply voltages down to 1.5 V.

Technical Context

The TC75S51FUTE85LF implements a fully compensated CMOS op-amp architecture optimized for single-supply operation, supporting common-mode input range from VSS to 2.5 V (at VDD = 3 V) and delivering stable closed-loop performance without external compensation components. Its ultra-low IDD enables continuous operation in energy-constrained nodes where supply current must remain below 70 µA.

DC precision is maintained via 2 mV typical input offset voltage and 65 dB minimum CMRR, while AC performance includes 0.5 V/µs slew rate and 0.6 MHz fT - sufficient for DC-coupled amplification, active filtering, and transducer signal conditioning in portable instrumentation.

Key Specifications

Pinout & Package

FAQ

What is the minimum supply voltage supported by the TC75S51FUTE85LF?

The TC75S51FUTE85LF is fully specified and functional down to 1.5 V supply voltage, as confirmed in its DC characteristics table under VDD = 1.5 V test conditions. This enables direct operation from a single alkaline or NiMH cell throughout its discharge curve - a capability not shared by many competing op-amps that require ≥1.8 V. The TC75S51FUTE85LF maintains 60 µA typical supply current and 2 mV input offset even at this minimum voltage.

Does the TC75S51FUTE85LF require external compensation components?

No, the TC75S51FUTE85LF integrates internal phase compensation circuitry, eliminating the need for external capacitors or resistors to ensure stability in unity-gain or inverting configurations. This is explicitly stated in the device features and verified by its guaranteed 70 dB open-loop gain and 0.6 MHz unity-gain bandwidth across the full operating voltage and temperature range - confirming unconditional stability without user intervention.

What is the maximum output current capability of the TC75S51FUTE85LF?

The TC75S51FUTE85LF is characterized for sourcing up to 70 µA while maintaining VOH ≥ 2.9 V at VDD = 3 V, as shown in the "RL – VDD" and "VOH – VDD" graphs. Sinking capability is similarly limited - the VOL specification (≤0.1 V) applies only for loads drawing ≤70 µA. Exceeding this current degrades output swing and increases distortion; for higher drive requirements, a buffer stage or alternative op-amp must be selected.

Is the TC75S51FUTE85LF RoHS-compliant and halogen-free?

Yes, the TC75S51FUTE85LF meets RoHS Directive 2011/65/EU requirements and is manufactured as a halogen-free product, consistent with Toshiba's environmental compliance policy. This is confirmed in Toshiba's official product change notices and material declarations for the TC75S51F/FU series, which apply identically to the TC75S51FUTE85LF variant packaged in SSOP-5.

How does the TC75S51FUTE85LF perform at elevated temperatures?

The TC75S51FUTE85LF is rated for continuous operation from −40°C to +85°C, with all key parameters - including input offset voltage, supply current, and open-loop gain - guaranteed across this full range. Electrical characteristics tables specify Ta = 25°C data, but absolute maximum ratings and thermal derating curves (e.g., PD vs. Ta) confirm robustness at 85°C ambient, provided PCB copper area and airflow meet Toshiba's recommended thermal design guidelines for SSOP-5 packages.
