Product details
Overview
TC75S67TU,LF from Toshiba Electronic Devices & Storage Corporation is a single ultra-low-noise CMOS operational amplifier optimized for precision analog signal conditioning in battery-powered and space-constrained systems. It delivers 6 nV/√Hz input voltage noise at 1 kHz, 430 μA supply current at 2.5 V, and operates from 2.2 V to 5.5 V supply rails - enabling high-fidelity audio front-ends and sensor amplification in portable medical devices.
For engineers reviewing the TC75S67TU,LF datasheet, TC75S67TU,LF pinout, TC75S67TU,LF application, or TC75S67TU,LF equivalent, key selection criteria include its ultra-low noise floor, rail-to-rail input common-mode range (0–1.4 V at 2.5 V), 3.5 MHz unity-gain bandwidth, 100 dB open-loop gain, and guaranteed operation across –40°C to +85°C industrial temperature range.
Technical Context
The TC75S67TU,LF employs a fully differential CMOS input stage with p-channel input transistors, enabling femtoampere-level input bias current (1 pA typ.) and ultra-low input offset voltage drift (2 μV/°C typ.). Its internal compensation ensures stable unity-gain operation with ≥55° phase margin and supports capacitive loads up to 100 pF without oscillation when properly decoupled.
This op-amp is designed for low-voltage, low-power precision applications where noise performance dominates design trade-offs - not general-purpose amplification. It excludes voltage-follower use per datasheet restriction and requires strict adherence to common-mode input voltage limits (0–1.4 V at 2.5 V) to avoid instability.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-noise operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Higher input offset voltage (2 μV max), lower noise (5.5 nV/√Hz), 17 μA supply current | Better for ultra-low-power sensor nodes; less suitable for high-gain DC-stable designs due to chopper artifacts | Select when sub-μA quiescent current is critical and chopper-induced ripple is acceptable |
| MCP6V81T-E/OT | Zero-drift architecture, 0.25 μV offset, 13 nV/√Hz noise, 600 μA supply current | Superior DC accuracy for long-term thermocouple monitoring; higher noise limits audio/sensor front-end use | Select when microvolt-level offset stability over time/temperature outweighs noise priority |
Compared with OPA333AIDBVR and MCP6V81T-E/OT, the TC75S67TU,LF uniquely balances ultra-low noise (6 nV/√Hz), ultra-low bias current (1 pA), and moderate quiescent current (430 μA) - making it optimal for high-fidelity, battery-operated analog front-ends where both AC signal integrity and DC precision matter.

FAQ
What is the maximum supply voltage for TC75S67TU,LF?
The absolute maximum supply voltage for TC75S67TU,LF is 6 V across VDD and VSS terminals. However, the recommended operating range is 2.2 V to 5.5 V. Exceeding 5.5 V may cause irreversible damage, and operation above this range voids reliability guarantees per Toshiba's Absolute Maximum Ratings table.
Does TC75S67TU,LF support rail-to-rail output swing?
No, TC75S67TU,LF does not feature rail-to-rail output. At VDD = 2.5 V and RL ≥ 100 kΩ, the output high voltage (VOH) is specified at ≥2.4 V and output low voltage (VOL) at ≤0.1 V - yielding ~0.1 V headroom from each rail. This limitation must be accounted for in ADC interface design and level-shifting stages.
Can TC75S67TU,LF be used in a voltage-follower configuration?
No - the TC75S67TU,LF datasheet explicitly prohibits use in voltage-follower circuits. Doing so violates the common-mode input voltage constraint and significantly increases risk of oscillation. Stable operation requires closed-loop gain ≥2 and adherence to the specified CMVIN range (0–1.4 V at 2.5 V).
What is the thermal resistance (θJA) of the TC75S67TU,LF UFV package?
The TC75S67TU,LF UFV package has a junction-to-ambient thermal resistance (θJA) of 350°C/W when mounted on a standard 30 mm × 30 mm glass epoxy board with 35 mm² pad area. This value assumes no additional copper pour or thermal vias - PCB layout improvements can reduce θJA by up to 40%.
Is TC75S67TU,LF RoHS compliant and lead-free?
Yes, TC75S67TU,LF is RoHS compliant and lead-free. Toshiba confirms compliance with EU Directive 2011/65/EU (RoHS 2) and JEDEC J-STD-609 moisture sensitivity level 1 (MSL-1). The ",LF" suffix explicitly denotes lead-free termination, and the device meets JEDEC standard SnAgCu (SAC305) solder compatibility requirements.
