Product details
Overview
TLV2772ID from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for precision analog signal conditioning in automotive and industrial systems. It delivers 5.1 MHz gain-bandwidth, 10.5 V/µs slew rate, 360 µV input offset voltage, 17 nV/√Hz input noise, and operates from 2.5 V to 5.5 V single supply - enabling high-fidelity sensor interfacing and ADC driver applications at −40°C to 125°C.
For engineers reviewing the TLV2772ID datasheet, TLV2772ID pinout, TLV2772ID application, or TLV2772ID equivalent, this page provides verified package mapping (SOIC-8), confirmed rail-to-rail output swing, low THD+N (0.005% into 600 Ω), micropower shutdown (<1 µA/channel), and validated performance across extended temperature range - critical for automotive sensor front-ends and portable instrumentation design.
Technical Context
The TLV2772ID uses a CMOS input stage with 2 pA input bias current and 10¹² Ω differential input resistance, supporting high-impedance sensor interfaces. Its unity-gain-stable architecture achieves 46° phase margin with 600 Ω load and 100 pF capacitance, ensuring robust stability in driving capacitive loads like ADC reference inputs.
It features rail-to-rail output swing (within 100 mV of rails at 2.2 mA), enabling full dynamic range utilization in low-voltage 2.7 V–5.5 V systems. The device includes no internal shutdown control logic - the I-suffix variant lacks shutdown functionality, distinguishing it from TLV2770/2773 variants with SHDN pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5.1 MHz - supports stable closed-loop operation up to ~400 kHz at gain = 12 without peaking. |
| Slew rate | 10.5 V/µs - enables clean 1-Vpp, 1-MHz sine wave reproduction without distortion. |
| Input offset voltage | 360 µV max - ensures ≤0.014% error in 2.5-V full-scale 12-bit ADC interface. |
| Supply current per channel | 1 mA - allows dual op-amp operation within 2 mA total, suitable for battery-powered sensors. |
| Operating temperature | −40°C to 125°C - qualified for under-hood automotive and industrial control environments. |

| THD+N | 0.005% into 600 Ω - meets telecom line-driver spectral purity requirements at 1 kHz. |
Pinout & Package
TLV2772ID is supplied in an 8-pin SOIC (Small Outline Integrated Circuit) package, surface-mount compatible, with standard JEDEC MS-012AC footprint (body width 3.9 mm, lead pitch 1.27 mm). Thermal resistance θJA = 120°C/W.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel 1) | High-impedance node accepting differential feedback; referenced to GND for inverting configurations. |
| 2 | Non-inverting input (Channel 1) | Accepts high-Z sensor signals; common-mode range extends to rail (GND to VDD −1.3 V). |
| 3 | Output (Channel 1) | Rail-to-rail capable: swings within 100 mV of VDD/GND at 2.2 mA load. |
| 4 | Ground | Common return path for both channels; must be low-impedance to minimize PSRR degradation. |
| 5 | Non-inverting input (Channel 2) | Independent input for second amplifier; shares same VDD/GND with Channel 1. |
| 6 | Inverting input (Channel 2) | Supports dual independent gain stages or composite amplifier topologies. |
| 7 | Output (Channel 2) | Electrically isolated output; drives separate loads without crosstalk (typical isolation > 80 dB). |
| 8 | Positive supply (VDD) | Accepts 2.5–5.5 V; supply rejection ratio ≥70 dB ensures immunity to digital supply noise. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers full 2.5-V to 5.5-V output swing range, maximizing ADC input utilization and dynamic range. |
| Low input bias current | 2 pA typical enables direct connection to high-impedance pH electrodes, piezoelectric sensors, and photodiode transimpedance nodes. |
| Low distortion into 600 Ω | 0.005% THD+N at 1 kHz allows use as line driver in telecom and audio codec reference circuits. |
| Extended temperature range | Specified from −40°C to 125°C with guaranteed parameters - eliminates derating for engine control unit (ECU) designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C offset drift), lower noise (12 nV/√Hz), but higher supply current (17 µA/channel) and narrower GBW (350 kHz). | Better for ultra-low-drift DC applications (e.g., weigh scales); unsuitable for >100 kHz signal paths due to limited bandwidth. | Select OPA2333AIDR when long-term DC stability dominates over speed and power; avoid when >100 kHz small-signal bandwidth required. |
| LMV722QDR | Lower cost, rail-to-rail I/O, 10 MHz GBW, but higher offset (1.25 mV), higher noise (20 nV/√Hz), and only rated to 105°C. | Acceptable for non-automotive industrial controls; not qualified for AEC-Q100 or extended-temp automotive use. | Select LMV722QDR for cost-sensitive consumer or commercial equipment; avoid for automotive or military-grade designs requiring −40°C to 125°C operation. |
Compared with OPA2333AIDR and LMV722QDR, TLV2772ID uniquely balances 5.1 MHz bandwidth, 360 µV offset, 17 nV/√Hz noise, and AEC-Q100-compatible −40°C to 125°C operation - making it optimal for automotive sensor signal chains where speed, precision, and temperature resilience are simultaneously required.

FAQ
What is the maximum operating temperature range for TLV2772ID?
The TLV2772ID is specified for continuous operation from −40°C to 125°C ambient temperature. This rating is validated per TI's automotive qualification standards and includes full electrical parameter guarantees across the entire range - including input offset voltage, CMRR, and open-loop gain - making it suitable for under-hood automotive applications and industrial control cabinets without thermal derating.
Does TLV2772ID include a shutdown pin?
No, TLV2772ID does not include a shutdown pin. Unlike TLV2770 or TLV2773 variants, the TLV2772ID (and all TLV2772-x variants) lacks dedicated shutdown functionality. Its quiescent current remains at 1 mA per channel across the full supply range; power reduction requires external supply gating. This simplifies layout but precludes dynamic power cycling in battery-operated systems.
What is the input common-mode voltage range for TLV2772ID?
The input common-mode voltage range for TLV2772ID is 0 V to VDD − 1.3 V at 25°C, and maintains ≥60 dB CMRR across this range. For example, at VDD = 5 V, inputs may swing from GND to 3.7 V. This excludes true rail-to-rail input capability but supports most single-supply sensor interfaces where the signal stays above GND and below mid-rail.
Can TLV2772ID drive a 600-Ω load with low distortion?
Yes, TLV2772ID is characterized for 0.005% THD+N into a 600-Ω load at 1 kHz with AV = 1, VDD = 5 V. This performance is enabled by its high output drive strength (±2.2 mA) and rail-to-rail output swing, allowing clean signal delivery to legacy telecom line receivers, audio codecs, and test equipment inputs without external buffering.
Is TLV2772ID pin-compatible with other TLV277x devices in SOIC-8 package?
Yes, TLV2772ID is pin-compatible with TLV2772CD, TLV2772AID, and TLV2772IP in the SOIC-8 (D) package - sharing identical pin 1 orientation, pinout, and footprint. However, it is not pin-compatible with TLV2771 (single-channel, 5-pin SOT-23) or TLV2774 (quad-channel, 14-pin SOIC), nor with TLV2772 variants in MSOP-8 (DGK) or TSSOP-8 (PW) packages due to differing pin assignments.
