Product details
Overview
TLV2772AMDG4 from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for high-speed, low-power precision applications. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, and 360 µV input offset voltage at 5 V supply, with micropower shutdown (<1 µA per channel) and operation across −55°C to 125°C. It is used in automotive sensor signal conditioning where wide temperature range and rail-to-rail output drive into ADC reference inputs are critical.
For engineers reviewing the TLV2772AMDG4 datasheet, TLV2772AMDG4 pinout, TLV2772AMDG4 application, or TLV2772AMDG4 equivalent, key selection considerations include its guaranteed −55°C to 125°C military-grade temperature rating, 2-pA input bias current enabling high-impedance source interfacing, and 0.005% THD+N driving 600-Ω loads for telecom line drivers and precision data acquisition front-ends.
Technical Context
The TLV2772AMDG4 employs a CMOS input stage with differential pair architecture, enabling ultra-low input bias current (2 pA typ) and high input impedance (>1 TΩ). Its fully complementary output stage supports true rail-to-rail swing (within 100 mV of rails at 1.3 mA load) while maintaining stability with capacitive loads up to 100 pF.
It integrates independent micropower shutdown control per channel, reducing quiescent current to <1 µA per channel without affecting adjacent channel operation. The device is characterized for full parametric performance over −55°C to 125°C, with input offset voltage drift of only 2 µV/°C - critical for uncalibrated automotive and industrial systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical - enables accurate reproduction of fast transients in sensor interfaces and active filters. |
| Gain-Bandwidth Product | 5.1 MHz typical - supports stable unity-gain buffer configurations and closed-loop gains up to ~10 at 500 kHz. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤1 LSB error in 12-bit ADC systems with 2.5 V reference. |
| Supply Current (per channel) | 1 mA typical at 5 V - allows dual op-amp operation within 2 mA total, suitable for battery-powered modules. |
| Input Bias Current | 2 pA typical - preserves signal integrity when amplifying from high-impedance sources like piezoelectric sensors. |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom voice-grade distortion requirements without external compensation. |

Pinout & Package
TLV2772AMDG4 is packaged in an 8-pin MSOP (DGK) with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm. This thermally enhanced package supports reliable operation at full rated junction temperature under continuous 1 mA/channel load.
| Pin/Terminal | 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) | High-Z input for single-ended signal injection; 2-pA bias current minimizes voltage drop across source impedances >100 MΩ. |
| 3 | Output (Channel 1) | Rail-to-rail capable output driving ≥1.3 mA; settles to 0.01% in 0.6 µs with 600-Ω load. |
| 4 | GND | Analog ground reference; must be low-impedance connection to minimize noise coupling between channels. |
| 5 | VDD+ | Positive supply input (2.5–5.5 V); decoupling capacitor required within 5 mm for stability at high frequencies. |
| 6 | Non-inverting Input (Channel 2) | Independent high-Z input; identical electrical specs to Pin 2 - enables dual-sensor parallel processing. |
| 7 | Inverting Input (Channel 2) | Matches Pin 1 behavior; supports matched dual-channel instrumentation topologies without inter-channel crosstalk. |
| 8 | Output (Channel 2) | Functionally identical to Pin 3; enables simultaneous dual-channel buffering or differential output generation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 100 mV of VDD and GND at 1.3 mA load - eliminates level-shifting circuitry for ADC reference buffers. |
| Micropower shutdown mode | Reduces per-channel IDD to <1 µA - enables duty-cycled sensor amplification in energy-constrained automotive ECUs. |
| Low THD+N (0.005%) | Meets ITU-T G.712 voiceband linearity spec - suitable for analog front-ends in VoIP gateways and modem ICs. |
| Extended temperature range | Full parametric guarantee from −55°C to 125°C - validated for engine control modules and brake-by-wire systems. |
| Ultra-low input bias current | 2 pA typical - prevents signal attenuation in pH probe, thermopile, or photodiode transimpedance stages. |

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 |
|---|---|---|---|
| TLV2772IDGKR | Same silicon, but rated for −40°C to 125°C (I-temp) and packaged in tape-and-reel MSOP-8; no military qualification. | Lacks Q/M-level automotive/military qualification; not approved for under-hood or avionics use. | Select when cost-sensitive industrial designs do not require extended temperature validation or AEC-Q100 compliance. |
| OPA2333AIDRGT | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2772AMDG4's 2 µV/°C; higher 350 nA input bias current. | Better DC accuracy for long-term sensor calibration; less suitable for high-Z sources due to higher IB. | Choose for ultra-stable DC-coupled measurement where offset drift dominates error budget, not high-impedance interfacing. |
Compared with TLV2772IDGKR, TLV2772AMDG4 provides guaranteed −55°C operation and military-grade reliability documentation, while OPA2333AIDRGT trades ultra-low drift for higher input current - making TLV2772AMDG4 optimal for high-Z, wide-temperature analog signal chains where drift is secondary to bias current and thermal robustness.

FAQ
What is the maximum operating temperature range for TLV2772AMDG4?
The TLV2772AMDG4 is fully specified and tested from −55°C to 125°C ambient temperature. This military-grade temperature range is validated per TI's M-level qualification standards and includes guaranteed performance for input offset voltage, slew rate, and supply current across the entire span - essential for under-hood automotive and defense applications where thermal stress is extreme.
Does TLV2772AMDG4 support rail-to-rail input common-mode range?
No, TLV2772AMDG4 features rail-to-rail *output* swing but not rail-to-rail input. Its common-mode input voltage range extends from GND to VDD − 1.3 V at 2.7 V supply, and GND to VDD − 1.3 V at 5 V supply. This means the inputs cannot accept signals within 1.3 V of VDD, limiting direct single-supply interfacing to signals below that threshold unless level-shifted.
How does the shutdown function operate on TLV2772AMDG4?
The TLV2772AMDG4 does not include a dedicated shutdown pin. Shutdown functionality is not implemented in this variant - unlike TLV2773/TLV2775, which integrate SHDN pins. TLV2772AMDG4 operates continuously when powered; power gating must be managed externally via VDD control or system-level sleep sequencing.
What package type is used for TLV2772AMDG4 and is it RoHS-compliant?
TLV2772AMDG4 uses the DGK package: an 8-pin MSOP with exposed thermal pad, dimensions 3.0 mm × 3.0 mm × 1.0 mm. It is lead-free and RoHS-compliant per TI's standard packaging policy, with JEDEC-standard moisture sensitivity level (MSL) 3 and compatible with standard reflow profiles including Pb-free soldering at peak 260°C.
Can TLV2772AMDG4 drive a 600-Ω load while maintaining low distortion?
Yes - TLV2772AMDG4 is explicitly characterized for 0.005% THD+N when driving a 600-Ω load at 1 kHz with AV = 1, VDD = 5 V. This performance is enabled by its high slew rate (10.5 V/µs) and robust output stage, making it suitable for telecom line drivers, audio codecs, and other applications demanding voiceband fidelity without external output buffers.
