Product details
Overview
TLV2772AIP from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for precision analog signal conditioning in single-supply systems. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage (max), 1 mA per-channel supply current, and operates from 2.5 V to 5.5 V - enabling high-fidelity sensor front-ends and ADC driver stages in automotive and industrial instrumentation.
For engineers reviewing the TLV2772AIP datasheet, TLV2772AIP pinout, TLV2772AIP application, or TLV2772AIP equivalent, this page provides verified electrical specifications, temperature-rated performance across −40°C to 125°C, package-specific pin mapping for PDIP-8, and validated alternative options for low-power, rail-to-rail op-amp selection in space-constrained embedded designs.
Technical Context
The TLV2772AIP implements a CMOS input stage with 2 pA typical input bias current and 17 nV/√Hz input noise voltage at 10 kHz, supporting high-impedance source interfacing without significant DC error or noise degradation. Its rail-to-rail output swing enables full utilization of ADC reference ranges when driving 12-bit+ converters.
It features micropower shutdown mode (IDD < 1 µA per channel) and is characterized over extended temperature (−40°C to 125°C), meeting Q-Temp automotive qualification requirements. The device maintains 0.005% THD+N into 600 Ω, confirming suitability for telecom line-driver and audio preamplifier roles where distortion must remain below audible thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ - supports fast transient response in active filters and buffer stages without slew-induced distortion. |
| Gain-Bandwidth Product | 5.1 MHz typ - enables stable unity-gain and non-inverting configurations up to ~500 kHz with adequate phase margin. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.009% full-scale error in 4-V span 12-bit ADC interfaces. |
| Supply Current (per channel) | 1 mA typ at 2.7 V - allows dual-channel operation under 2.1 mW total power in battery-powered portable sensors. |
| Rail-to-Rail Output | Swings within 100 mV of VDD and GND at 2.2 mA load - maximizes dynamic range when interfacing with 3.3-V or 5-V SAR ADCs. |
| Input Noise Voltage | 17 nV/√Hz at 10 kHz - preserves SNR in low-level transducer amplification (e.g., thermocouple, strain gauge). |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets Class D audio preamp and telecom line-driver spectral purity requirements. |
Pinout & Package
TLV2772AIP is supplied in an 8-pin plastic DIP (PDIP) package with through-hole mounting and standard 0.3-inch body width. 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 | OUT A | Inverting amplifier output - drives external loads up to ±50 mA; rail-to-rail swing enables direct connection to ADC inputs. |
| 2 | IN− A | Inverting input - high-impedance CMOS node (10¹² Ω); requires matched trace impedance for optimal CMRR. |
| 3 | IN+ A | Non-inverting input - referenced to system ground or bias network; accepts signals from 0 V to VDD − 1.3 V. |
| 4 | GND | Analog ground reference - must be star-connected to minimize noise coupling between channels. |
| 5 | IN+ B | Non-inverting input for second amplifier - independent of Channel A; supports differential pair or dual-sensor conditioning. |
| 6 | IN− B | Inverting input for second amplifier - electrically isolated from Channel A; enables separate feedback networks. |
| 7 | OUT B | Output for second amplifier - identical AC/DC specs to OUT A; usable for dual-path signal processing or redundancy. |
| 8 | VDD | Positive supply rail - accepts 2.5 V to 5.5 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale signal headroom to 12-bit+ ADCs without level-shifting circuitry or supply overhead. |
| Micropower shutdown mode | Reduces per-channel current to <1 µA - enables duty-cycled sensing in energy-harvesting IoT nodes. |
| Extended temperature rating | Specified from −40°C to 125°C - qualified for under-hood automotive and industrial control cabinet deployment. |
| Low THD+N into 600 Ω | 0.005% at 1 kHz - eliminates need for post-amplifier filtering in telecom voice-band and audio line-driver applications. |
| High CMRR (84 dB min) | Maintains accuracy in noisy environments (e.g., motor drive feedback, PLC analog I/O) with common-mode interference up to 100 mV. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2772IDR | Same core specs but in SOIC-8 package; no internal leadframe; rated −40°C to 125°C (I-suffix), not automotive-qualified. | Lacks Q-Temp automotive qualification and PDIP through-hole mounting; suited for surface-mount PCBs with tighter layout constraints. | Select TLV2772IDR only if SOIC-8 footprint and RoHS-compliant reflow assembly are required; avoid for automotive under-hood use. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2772AIP's 2 µV/°C; higher 350 nA input bias current; 17 µA supply current per channel. | Better long-term DC stability in precision weigh scales or data loggers; higher quiescent current limits battery life in portable devices. | Choose OPA2333AIDR when ultra-low drift dominates over power budget; TLV2772AIP remains preferred for cost-sensitive, low-power dual-channel apps. |
Compared with TLV2772IDR, TLV2772AIP offers automotive qualification and through-hole reliability; versus OPA2333AIDR, it trades zero-drift performance for 17× lower supply current and lower cost - making TLV2772AIP optimal for high-volume, thermally robust, battery-aware dual-op-amp implementations.

FAQ
What is the operating temperature range for TLV2772AIP?
The TLV2772AIP is specified for operation from −40°C to +125°C and is qualified to Q-Temp automotive standards. This extended range ensures reliable performance in under-hood automotive ECUs, industrial control cabinets, and outdoor environmental monitoring equipment where ambient temperatures exceed commercial-grade limits.
Does TLV2772AIP support rail-to-rail input capability?
No, TLV2772AIP features rail-to-rail *output* swing only. Its common-mode input voltage range extends from GND to VDD − 1.3 V (at 2.7 V supply), meaning the inputs cannot accept signals all the way to VDD. For true rail-to-rail input/output, consider TI's TLV2462 or OPA2376 families instead.
What is the maximum load current TLV2772AIP can drive per channel?
TLV2772AIP guarantees ±50 mA output current per channel under absolute maximum ratings. In practical linear operation, it delivers ±2.2 mA while maintaining rail-to-rail swing and low distortion - sufficient for driving ADC reference buffers, small relays, or 600 Ω telecom lines without external boost circuitry.
Is TLV2772AIP pin-compatible with other TLV277x variants in PDIP-8?
Yes, TLV2772AIP shares identical pinout and footprint with TLV2772CP, TLV2772IP, and TLV2772QP in the 8-pin PDIP package. All variants use the same Channel A/B input/output/GND/VDD arrangement - enabling drop-in replacement across temperature grades without PCB redesign.
How does TLV2772AIP perform in shutdown mode?
In shutdown mode, TLV2772AIP draws less than 1 µA per channel (typical 0.8 µA), reducing total quiescent current to under 2 µA for both amplifiers. This enables ultra-low-power wake-on-event architectures in battery-operated sensors, where the device remains in shutdown until triggered by an external interrupt or timer.
