Product details
Overview
TLV2772CP from Texas Instruments is a dual-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 and 5.1 MHz gain-bandwidth product while consuming only 1 mA per channel. It features 360 µV input offset voltage, 17 nV/√Hz input noise, and micropower shutdown mode (<1 µA), making it suitable for precision analog front-ends in portable instrumentation and automotive sensor signal conditioning.
For engineers reviewing the TLV2772CP datasheet, TLV2772CP pinout, TLV2772CP application, or TLV2772CP equivalent, key selection considerations include its rail-to-rail output swing into 600-Ω loads (0.005% THD+N), extended temperature range (0°C to 70°C), and compatibility with low-voltage ADC reference driving and telecom line driver circuits.
Technical Context
The TLV2772CP employs a CMOS input stage with 2 pA input bias current and high differential input resistance (>10¹² Ω), enabling high-impedance source interfacing without significant error. Its unity-gain-stable architecture supports closed-loop gains ≥1 with 46° phase margin at 600-Ω load and 100-pF capacitance.
It operates across a 2.5–5.5-V supply range with rail-to-rail output swing (within 100 mV of rails at 2.2 mA), common-mode input range extending to GND, and robust CMRR (≥60 dB over full temperature range) - critical for DC-coupled sensor amplification in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical - enables accurate reproduction of fast transient signals up to ~1.7 MHz at unity gain. |
| Gain-Bandwidth Product | 5.1 MHz typical - supports stable closed-loop gain of 10 at ~500 kHz with adequate phase margin. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.036% gain error in 1-V full-scale precision amplification. |
| Supply Current (per channel) | 1 mA typical at 2.7 V - allows dual-channel operation under 2.1 mW total power at 2.7 V. |
| Input Noise Voltage | 17 nV/√Hz at 10 kHz - maintains SNR >95 dB for 20-kHz bandwidth audio or sensor signals. |
| Rail-to-Rail Output | Swings within 100 mV of VDD/GND at 2.2 mA - maximizes dynamic range when driving ADC inputs directly. |
| Shutdown Current | <1 µA per channel - reduces system standby power by >99.9% versus active mode. |
Pinout & Package
TLV2772CP is housed in an 8-pin plastic DIP (dual in-line package) with through-hole mounting. Pin 1 is located at the left end of the top row, identified by a beveled edge or molded dot.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must remain unconnected or grounded per layout best practice. |
| 2 | Inverting Input (Ch1) | High-impedance CMOS node accepting differential input signals; bias current ≤2 pA. |
| 3 | Non-inverting Input (Ch1) | High-impedance CMOS node; common-mode range extends to GND for single-supply use. |
| 4 | GND | Analog ground reference for both channels; requires low-impedance connection to system ground plane. |
| 5 | VDD | Positive supply rail (2.5–5.5 V); decoupling capacitor (0.1 µF) required near pin. |
| 6 | Output (Ch1) | Capable of sourcing/sinking ±2.2 mA while maintaining rail-to-rail swing into 600-Ω load. |
| 7 | Inverting Input (Ch2) | Independent second channel input; electrically isolated from Ch1 except via shared supply/ground. |
| 8 | Non-inverting Input (Ch2) | Second channel non-inverting input; identical electrical characteristics to Pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range into ADC reference buffers and low-voltage data acquisition systems without level-shifting circuitry. |
| Low THD+N (0.005%) | Enables high-fidelity signal amplification in telecom line drivers and audio preamps where harmonic distortion must be minimized. |
| Extended temperature range (0°C to 70°C) | Validated performance across commercial ambient conditions - suitable for consumer electronics and industrial control panels. |
| Micropower shutdown mode | Reduces quiescent current to <1 µA per channel, enabling battery-powered devices to achieve multi-year standby life. |
| High CMRR (≥60 dB) | Rejects common-mode noise from motor drives or switching supplies, preserving accuracy in noisy embedded systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462CP | Lower slew rate (1.6 V/µs), higher supply current (550 µA/channel), rail-to-rail I/O, wider VDD range (2.7–6 V). | Better DC precision (150 µV VIO), but insufficient speed for >100-kHz signal paths. | Select when ultra-low offset and rail-to-rail input are prioritized over bandwidth and power efficiency. |
| OPA2340PA | Higher slew rate (6 V/µs), lower noise (12 nV/√Hz), rail-to-rail output, fixed 5-V operation only. | Superior AC performance and noise floor, but lacks 2.5-V operation and shutdown mode. | Select when operating strictly at 5 V and requiring lower noise than TLV2772CP in medical or test equipment. |
Compared with TLV2772CP, TLV2462CP trades bandwidth and power for improved DC accuracy and input rail-to-rail capability, while OPA2340PA offers better noise and speed at the cost of supply flexibility and shutdown functionality - making TLV2772CP optimal for battery-powered, wide-supply, moderate-speed precision applications.

FAQ
What is the maximum supply voltage for TLV2772CP?
The absolute maximum supply voltage for TLV2772CP is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation beyond 5.5 V risks permanent damage and invalidates parametric guarantees. At 5 V, TLV2772CP delivers full-rated performance including 10.5 V/µs slew rate and 5.1 MHz bandwidth, while maintaining rail-to-rail output swing and low distortion.
Does TLV2772CP support rail-to-rail input?
No, TLV2772CP supports rail-to-rail output only - its input common-mode range extends to GND but not to VDD (limited to VDD − 1.3 V). This design enables robust operation with single-supply sensors referenced to ground while avoiding input stage saturation. For true rail-to-rail input capability, consider TI's TLV2462CP or OPA2340PA as alternatives.
What is the typical input bias current of TLV2772CP?
The typical input bias current of TLV2772CP is 2 pA at 25°C, with a maximum of 60 pA over the full 0°C to 70°C temperature range. This ultra-low value results from its CMOS input stage and enables high-impedance sensor interfacing - such as piezoelectric transducers or pH electrodes - without significant input loading error or DC offset drift.
Can TLV2772CP drive a 600-Ω load with low distortion?
Yes, TLV2772CP is specifically characterized for 600-Ω loads, delivering 0.005% THD+N at 1 kHz with AV = 1. Its rail-to-rail output stage provides ±2.2 mA drive capability, ensuring minimal clipping and harmonic generation when interfacing with legacy telecom line standards or audio codecs requiring 600-Ω termination.
Is TLV2772CP pin-compatible with other TLV277x variants?
TLV2772CP (8-pin PDIP) shares the same pinout as TLV2772CD (SOIC-8) and TLV2772ID (SOIC-8, industrial temp), but is not pin-compatible with MSOP-8 (DGK) or TSSOP-8 (PW) packages due to different physical layouts. All TLV2772 variants use identical functional pin assignments - Pin 2/3/6 for Channel 1, Pin 7/8 for Channel 2 - enabling direct PCB footprint substitution only within the same package family.
