Product details
Overview
TLV2772AMDREP from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for precision analog signal conditioning in extended-temperature industrial and defense systems. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, and operates from 2.5 V to 5.5 V single supply - enabling high-fidelity ADC driver and sensor interface applications across −55°C to 125°C.
For engineers reviewing the TLV2772AMDREP datasheet, TLV2772AMDREP pinout, TLV2772AMDREP application, or TLV2772AMDREP equivalent, this page provides verified electrical specifications, SOIC-8 package layout, military-grade temperature characterization, low-distortion driving capability for 600-Ω telecom loads, and validated alternatives for ruggedized analog front-end design.
Technical Context
The TLV2772AMDREP employs a CMOS input stage with 2 pA typical input bias current and 17 nV/√Hz input noise voltage at 10 kHz, supporting high-impedance sensor interfacing without significant error contribution. Its rail-to-rail output swing (within 100 mV of rails at 2.2 mA load) and 50 mA short-circuit output current enable direct connection to SAR and delta-sigma ADC reference inputs.
It features micropower shutdown mode (<1 µA per channel), characterized across full −55°C to 125°C range with 2 µV/°C input offset drift, and meets MIL-STD-883 ESD requirements (>2000 V HBM). The device lacks internal shutdown control - consistent with TLV2772 (non-S variant) family architecture per ordering table and pinout diagram.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V single supply - supports battery-powered and wide-input industrial rails without level-shifting. |
| Gain-Bandwidth Product | 5.1 MHz - enables stable unity-gain buffer operation up to ~4.8 MHz with 600-Ω load and 100-pF capacitance. |
| Slew Rate | 10.5 V/µs - ensures <3.92 µs settling to 0.01% for 1-V step into 600-Ω load, critical for fast data acquisition. |
| Input Offset Voltage | 360 µV max at 25°C - maintains <0.02% gain error in 12-bit sensor signal chains with 1-V full-scale range. |
| Input Bias Current | 2 pA typical - minimizes voltage error across >1-MΩ source impedances (e.g., piezoelectric sensors, pH electrodes). |
| THD+N @ 1 kHz | 0.005% into 600 Ω - preserves signal fidelity in telecom line drivers and audio preamps requiring low harmonic distortion. |
| Operating Temperature | −55°C to 125°C - qualified per JEDEC extended-temperature standards for avionics, downhole, and military platforms. |
Pinout & Package
TLV2772AMDREP is housed in an 8-pin SOIC (D) package with standard 1.27-mm pitch, 3.9-mm body width, and exposed pad not present. Pin assignments are fixed per TI SGLS317A datasheet Figure 3 (TLV2772 D/PW PACKAGE top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Delivers rail-to-rail buffered signal; capable of sourcing/sinking ±50 mA for direct ADC reference drive. |
| 2 | Channel 1 Inverting Input | High-impedance node (10¹² Ω) for feedback network connection; sensitive to PCB leakage at high source Z. |
| 3 | Channel 1 Non-Inverting Input | Accepts DC-biased sensor signals; common-mode range extends to GND and within 1.3 V of VDD at 2.7 V supply. |
| 4 | Ground | System return path; must be low-impedance star point to minimize PSRR degradation and crosstalk between channels. |
| 5 | Positive Supply | Accepts 2.5–5.5 V; bypass capacitor (0.1 µF ceramic) required within 5 mm for stability under dynamic load. |
| 6 | Channel 2 Output | Independent output; no internal coupling - allows dual-path signal conditioning (e.g., I/Q demodulation, differential sensing). |
| 7 | Channel 2 Inverting Input | Electrically isolated from Channel 1 inputs; enables independent gain/offset calibration per channel. |
| 8 | Channel 2 Non-Inverting Input | Matches Pin 3 performance; supports matched dual instrumentation amplifier front ends with external resistors. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives ADC references to within 100 mV of supply rails at 2.2 mA, maximizing dynamic range utilization. |
| Low input offset drift | 2 µV/°C max ensures <0.25 mV total offset shift over −55°C to 125°C, critical for uncalibrated field instruments. |
| High CMRR & PSRR | 82 dB min CMRR and 84 dB min PSRR suppress power supply noise and common-mode interference in noisy environments. |
| Low THD+N into 600 Ω | 0.005% at 1 kHz enables clean signal transmission in telecom line interfaces without post-amplifier filtering. |
| Extended temperature qualification | Controlled baseline with one assembly/test site and enhanced DMS support ensures long-term supply continuity for aerospace programs. |

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 1/f noise, but 350-kHz GBW and 0.16-V/µs slew rate. | Better for ultra-low-drift DC applications (e.g., precision weigh scales); unsuitable for >100-kHz signal conditioning due to bandwidth limitation. | Select OPA2333AIDR when sub-µV drift dominates over speed; choose TLV2772AMDREP when >5-MHz bandwidth and >10-V/µs slew are required. |
| LM7322MAX/NOPB | Higher 22-MHz GBW and 12-V/µs slew rate, but 2-mV max input offset and only rated to 125°C (not −55°C). | Preferred for high-speed active filters or video signal paths; lacks extended low-temperature qualification for space or arctic deployment. | Choose LM7322MAX/NOPB for speed-critical industrial automation; retain TLV2772AMDREP for full military-temperature compliance with precision-speed balance. |
Compared with OPA2333AIDR and LM7322MAX/NOPB, TLV2772AMDREP uniquely balances 5.1-MHz bandwidth, 10.5-V/µs slew rate, 360-µV offset, and full −55°C to 125°C qualification - making it the only option among the three qualified for unheated avionics bays and downhole telemetry systems.

FAQ
What is the operating temperature range of the TLV2772AMDREP?
The TLV2772AMDREP is fully characterized and qualified for continuous operation from −55°C to 125°C. This extended temperature range is achieved through controlled baseline manufacturing, JEDEC-compliant qualification (including HAST, temperature cycling, and bond intermetallic life testing), and is explicitly specified for the "M" suffix grade in the SGLS317A datasheet.
Does the TLV2772AMDREP include a shutdown pin?
No, the TLV2772AMDREP does not include a shutdown pin. It belongs to the base TLV2772 variant (non-"S" suffix), as confirmed by the FAMILY PACKAGE TABLE and TLV2772 pinout diagram in the datasheet - which shows Pins 1–8 assigned exclusively to dual-channel I/O and power, with no SHDN terminal. Shutdown functionality is only available in TLV2773/TLV2775 variants.
What is the maximum load capacitance the TLV2772AMDREP can drive stably?
The TLV2772AMDREP maintains stability with up to 100 pF capacitive load when driving a 600-Ω resistor, as verified in the Operating Characteristics tables (SGLS317A, pages 7 and 9). Phase margin remains at 46° under these conditions. For loads exceeding 100 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is required to prevent peaking or oscillation.
How does the input offset voltage of TLV2772AMDREP compare to standard commercial op-amps?
The TLV2772AMDREP specifies a maximum input offset voltage of 360 µV at 25°C - significantly lower than typical commercial-grade dual op-amps like LM358 (2–7 mV) or TLC272 (10 mV). This precision, combined with only 2 µV/°C drift, makes TLV2772AMDREP suitable for applications where offset-induced errors must remain below 0.1% over wide temperature excursions.
Is the TLV2772AMDREP RoHS compliant and lead-free?
Yes, the TLV2772AMDREP is RoHS compliant and lead-free. As an enhanced-product (EP) grade component from Texas Instruments, it adheres to J-STD-609 Category 1 marking and IPC/JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3), with lead-free terminations and halogen-free molding compound - fully documented in TI's official packaging and reliability reports for the SOIC-8 (D) package.
