Product details
Overview
TLV2772MDR 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, 360 µV input offset voltage, and 1 mA per-channel supply current across a 2.5 V to 5.5 V single supply - enabling accurate signal conditioning in automotive sensor interfaces and portable data acquisition systems.
For engineers reviewing the TLV2772MDR datasheet, TLV2772MDR pinout, TLV2772MDR application, or TLV2772MDR equivalent, this device is selected for its combination of wide temperature operation (−55°C to 125°C), micropower shutdown mode (<1 µA), and robust rail-to-rail output drive into 600-Ω loads with 0.005% THD+N - critical for high-fidelity analog front-ends in harsh-environment electronics.
Technical Context
The TLV2772MDR employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, supporting high-impedance sensor interfacing without significant loading or noise degradation. Its unity-gain-stable architecture achieves 46° phase margin with 600-Ω load and 100-pF capacitive load, ensuring stable operation in driving ADC reference inputs or active filters.
Designed for extended temperature reliability, the M-suffix variant meets military-grade thermal specifications (−55°C to 125°C) and is qualified per automotive standards. It operates down to 2.5 V while maintaining rail-to-rail output swing and 13 V/mV large-signal voltage gain - enabling precision amplification even at ultra-low supply voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical - enables faithful reproduction of fast-changing signals up to ~1.7 MHz full-power bandwidth into 10-kΩ load. |
| Gain-Bandwidth Product | 5.1 MHz typical - supports stable closed-loop gains ≥2 with >2.5 MHz small-signal bandwidth at unity gain. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.36 mV DC error in precision gain stages without trimming. |
| Supply Current (per channel) | 1 mA typical at 2.7 V - allows dual op-amp operation within 2 mA total, suitable for battery-powered instrumentation. |
| Rail-to-Rail Output | Swings within 100 mV of rails at 2.2 mA load - maximizes dynamic range when driving SAR or sigma-delta ADC inputs directly. |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - preserves signal fidelity in telecom line drivers and audio preamps. |
| Operating Temperature | −55°C to 125°C - validated for under-hood automotive, avionics, and industrial control environments. |
Pinout & Package
TLV2772MDR is packaged in an 8-pin SOIC (D package) with standard dual-op-amp pinout and no shutdown function. Pin 1 is the non-inverting input of Channel 1; Pin 2 is the inverting input of Channel 1; Pin 3 is the output of Channel 1; Pin 4 is GND; Pin 5 is the inverting input of Channel 2; Pin 6 is the non-inverting input of Channel 2; Pin 7 is the output of Channel 2; Pin 8 is VDD.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1IN+ | Non-inverting input of Channel 1 - high-impedance CMOS node (2 pA bias) for sensor or reference signal routing. |
| 2 | 1IN− | Inverting input of Channel 1 - used for feedback configuration; matched to Pin 1 for common-mode rejection. |
| 3 | 1OUT | Output of Channel 1 - rail-to-rail capable, drives 600-Ω loads with <0.005% THD+N at 1 kHz. |
| 4 | GND | Analog ground reference - must be low-impedance and separated from digital ground in mixed-signal PCB layouts. |
| 5 | 2IN− | Inverting input of Channel 2 - electrically identical to Pin 2; supports independent dual-channel configurations. |
| 6 | 2IN+ | Non-inverting input of Channel 2 - symmetrical to Pin 1; enables matched differential or dual-sensor amplification. |
| 7 | 2OUT | Output of Channel 2 - fully independent output stage; shares same AC/DC specs as Pin 3. |
| 8 | VDD | Positive supply rail - accepts 2.5 V to 5.5 V; bypass capacitor (0.1 µF) required near this pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| High Slew Rate + Wide GBW | 10.5 V/µs slew rate and 5.1 MHz GBW enable accurate amplification of multi-kHz sensor waveforms without phase lag or distortion. |

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 |
|---|---|---|---|
| TLV2772IDR | Same architecture and pinout; rated for −40°C to 125°C instead of −55°C to 125°C; 2.5 mV max VIO over full range vs. 1.9 mV for TLV2772MDR. | Approved for automotive AEC-Q100 Grade 2 but not military-qualified; lower cost for non-military temperature-critical designs. | Select TLV2772IDR when operating range ≥ −40°C suffices and qualification to MIL-PRF-38535 is not required. |
| OPA2333PAIDR | Zero-drift architecture; 2 µV max VIO, 0.02 µV/°C drift; higher 350 kHz GBW but only 0.16 V/µs slew rate; 17 µA per channel supply current. | Better DC precision for long-term stability, but insufficient slew rate for >10 kHz signal conditioning; unsuitable for driving 600-Ω telecom loads. | Select OPA2333PAIDR only for ultra-low-drift DC-coupled applications where speed and output drive are secondary. |
Compared with TLV2772IDR, TLV2772MDR provides tighter offset and extended cold-temperature capability essential for aerospace and defense systems; compared with OPA2333PAIDR, it trades DC precision for 65× higher slew rate and 58× lower quiescent current - making it optimal for wideband, low-power, high-reliability analog signal chains.

FAQ
What is the maximum operating temperature range for TLV2772MDR?
The TLV2772MDR is specified for continuous operation from −55°C to 125°C, meeting military-grade environmental requirements. This rating is validated per TI's QML-38535 flow and applies across all electrical parameters in the datasheet - unlike commercial variants such as TLV2772CDR (0°C to 70°C) or industrial TLV2772IDR (−40°C to 125°C). The M-suffix denotes full MIL-PRF-38535 qualification.
Does TLV2772MDR include a shutdown feature?
No, TLV2772MDR does not include a shutdown pin or internal shutdown circuitry. It is a standard dual op-amp variant in the TLV277x family - unlike TLV2770, TLV2773, and TLV2775, which integrate shutdown functionality. The TLV2772MDR draws 1 mA per channel continuously when powered; system-level power gating must be implemented externally if low-quiescent operation is required between measurements.
What package type is used for TLV2772MDR?
TLV2772MDR is supplied in an 8-pin SOIC (Small Outline Integrated Circuit) package, designated "D" in TI's packaging nomenclature. It measures 4.9 mm × 3.91 mm × 1.75 mm with 1.27-mm lead pitch. This surface-mount package is RoHS-compliant, halogen-free, and qualified for reflow soldering per JEDEC J-STD-020. No alternate packages (e.g., MSOP or TSSOP) are offered for the M-suffix variant.
Can TLV2772MDR drive a 600-Ω load with low distortion?
Yes, TLV2772MDR is explicitly characterized for 600-Ω load driving with 0.005% THD+N at 1 kHz and AV = 1, as confirmed in the datasheet's Operating Characteristics table (page 9, VDD = 5 V). Its rail-to-rail output stage delivers ±2.2 mA into 600 Ω while maintaining <100 mV headroom from supply rails - making it suitable for telecom line drivers, audio line outputs, and HART modem interfaces where harmonic distortion must remain below −86 dBc.
Is TLV2772MDR pin-compatible with other TLV277x dual op-amps?
Yes, TLV2772MDR is pin-compatible with all TLV2772-x variants in the SOIC-8 (D) package, including TLV2772CDR, TLV2772IDR, and TLV2772AQDR. All share identical pinout: Pin 1 (1IN+), Pin 2 (1IN−), Pin 3 (1OUT), Pin 4 (GND), Pin 5 (2IN−), Pin 6 (2IN+), Pin 7 (2OUT), Pin 8 (VDD). However, TLV2772MDR is not pin-compatible with TLV2773 or TLV2775, which use 10- or 14-pin packages and include shutdown pins.
