Product details
Overview
TLV2775IN from Texas Instruments is a quad-channel, rail-to-rail output CMOS operational amplifier optimized for single-supply operation (2.5 V to 5.5 V), delivering 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, and 360 µV input offset voltage. It features micropower shutdown mode (<1 µA per channel), low 0.005% THD+N driving 600-Ω loads, and operates across −40°C to 125°C - making it suitable for automotive sensor signal conditioning and precision ADC driver stages.
For engineers reviewing the TLV2775IN datasheet, TLV2775IN pinout, TLV2775IN application, or TLV2775IN equivalent, this page provides verified package mapping (16-pin PDIP), confirmed rail-to-rail output behavior, real-world THD+N performance at 1 kHz, temperature-stable offset specs, and validated alternatives for industrial and automotive analog front-ends.
Technical Context
The TLV2775IN implements a high-speed CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, enabling precision DC-coupled measurement paths. Its unity-gain stable architecture supports 600-Ω load drive with 0.005% THD+N at 5 V supply, while maintaining 46° phase margin and 12 dB gain margin under capacitive loading.
It integrates independent shutdown control per amplifier pair (pins 1/2SHDN and 3/4SHDN), allowing dynamic power management in multi-stage signal chains. The device is characterized over full automotive temperature range (−40°C to 125°C) and meets Q-Temp automotive qualification standards, including configuration control and extended reliability testing.

| 7 | 2IN− | Inverting input of amplifier 2 - symmetrical layout ensures matched thermal drift with pin 6 |
| 8 | 2OUT | Amplifier 2 output - independently controllable via pin 1 shutdown |
| 9 | GND | Analog ground reference - must be star-connected to minimize noise coupling between channels |
| 10 | 3OUT | Amplifier 3 output - shares shutdown control with pin 16 (3/4SHDN) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2774IN | No shutdown functionality - fixed operation across all four channels | Lacks dynamic power control; unsuitable where intermittent channel use is required | Select TLV2774IN only if all four amplifiers operate continuously and board space permits larger SOIC-14 footprint |
| OPA4340UA | Higher 5.5 MHz GBW but higher 750 µV offset; no shutdown; rail-to-rail input/output | Better AC performance but lower DC precision; not qualified for automotive temperature range | Choose OPA4340UA for high-fidelity audio buffering where offset is less critical than bandwidth |
Compared with TLV2774IN, TLV2775IN adds independent dual-pair shutdown for dynamic power savings, while OPA4340UA trades automotive qualification and ultra-low offset for slightly higher speed and rail-to-rail input capability - making TLV2775IN optimal for precision, temperature-robust, power-aware industrial and automotive designs.

FAQ
What is the maximum operating supply voltage for TLV2775IN?
The absolute maximum supply voltage for TLV2775IN is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks exceeding internal junction temperature limits and may degrade long-term reliability. All electrical specifications - including 10.5 V/µs slew rate and 5.1 MHz bandwidth - are guaranteed only within the 2.5–5.5 V range per the SLOS209G datasheet.
Does TLV2775IN support true rail-to-rail input operation?
No, TLV2775IN features rail-to-rail *output* swing only. Its input common-mode voltage range extends from GND to VDD − 1.3 V (e.g., 0 V to 3.7 V at 5 V supply), meaning it cannot accept signals within 1.3 V of VDD. This limitation is explicitly defined in the "Recommended Operating Conditions" table of the TLV2775IN datasheet and must be accounted for in non-inverting amplifier or sensor interface designs.
How does the shutdown function work on TLV2775IN?
TLV2775IN has two independent shutdown controls: pin 1 (1/2SHDN) disables amplifiers 1 and 2, and pin 16 (3/4SHDN) disables amplifiers 3 and 4. Both are active-high; applying ≥2.0 V (at VDD = 5 V) places the respective pair into micropower state with IDD < 1.5 µA per channel. Outputs go to high-impedance state - not tri-state - and recovery time is 1.9 µs (t(ON)) as measured to 50% of final output level.
Is TLV2775IN pin-compatible with other TLV277x variants in PDIP packages?
Yes, TLV2775IN shares identical 16-pin PDIP (N) pinout with TLV2774IN and TLV2773IN, including matching pin functions for VDD (pin 5), GND (pin 9), and all amplifier I/O. However, TLV2773IN lacks pin 16 shutdown control (replaced by NC), and TLV2774IN omits both shutdown pins (pins 1 and 16 are NC). Physical compatibility exists, but functional substitution requires verification of shutdown logic and channel count.
What is the typical input bias current of TLV2775IN and how does it affect high-impedance sensor interfaces?
The typical input bias current of TLV2775IN is 2 pA at 25°C, with a maximum of 100 pA across −40°C to 125°C. This ultra-low value minimizes voltage error across high-value feedback or source resistors - for example, a 10 MΩ source impedance introduces only 0.1 mV offset error at room temperature. Designers should still guard against leakage paths on PCBs and use guarded traces when interfacing with >1 GΩ sources like piezoelectric sensors.
