Product details
Overview
TLV2772IP from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for single-supply operation from 2.5 V to 5.5 V. 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 - enabling high-fidelity signal conditioning in portable and automotive sensor interfaces.
For engineers reviewing the TLV2772IP datasheet, TLV2772IP pinout, TLV2772IP application, or TLV2772IP equivalent, this device is selected for precision analog front-ends requiring low distortion (0.005% THD+N into 600 Ω), wide temperature operation (−55°C to 125°C), and micropower shutdown (<1 µA per channel).
Technical Context
The TLV2772IP uses a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, supporting high-impedance sensor interfacing. Its rail-to-rail output swing enables full utilization of ADC reference ranges when driving analog-to-digital converters.
It features micropower shutdown mode with fast turnon/turnoff times (2.4 µs / 444 ns), and is characterized across military-grade temperature extremes (−55°C to 125°C) in PDIP-8 package - meeting Q-Temp automotive and MIL-PRF-38535 requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical - supports fast transient response in active filters and buffer stages |
| Gain-Bandwidth Product | 5.1 MHz typical - enables stable unity-gain and closed-loop configurations up to ~1 MHz |
| Input Offset Voltage | 360 µV max at 25°C - ensures <1 LSB error when driving 12-bit ADCs with 2.5 V reference |
| Supply Current (per channel) | 1 mA typical at 2.7 V - enables dual op-amp operation under 2.5 mW total power budget |
| Rail-to-Rail Output | Swings within 100 mV of rails at 2.2 mA load - maximizes dynamic range into SAR or sigma-delta ADC inputs |
| Operating Temperature | −55°C to 125°C - qualified for under-hood automotive and industrial control environments |
| Shutdown Current | <1 µA per channel - extends battery life in intermittent-sampling systems |
Pinout & Package
TLV2772IP is supplied in an 8-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting. Pin 1 is identified by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | High-impedance node for feedback or differential sensing; 2 pA bias current minimizes resistor-induced offset |
| 2 | Non-Inverting Input (Channel 1) | Accepts high-Z sensor signals (e.g., thermocouples, bridge outputs) without loading |
| 3 | Output (Channel 1) | Rail-to-rail capable; drives 600 Ω loads with 0.005% THD+N for telecom line drivers |
| 4 | Ground | Common return for both channels; requires low-impedance PCB plane for noise immunity |
| 5 | Non-Inverting Input (Channel 2) | Independent input for dual-path signal conditioning (e.g., differential pair amplification) |
| 6 | Inverting Input (Channel 2) | Supports independent feedback networks per channel; no crosstalk between amplifiers |
| 7 | Output (Channel 2) | Matches Channel 1 performance; enables simultaneous dual-sensor readout |
| 8 | Positive Supply (VDD) | Accepts 2.5–5.5 V; internal regulation ensures stable biasing across supply variation |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale signal headroom into ADC references or DAC buffers without level-shifting circuitry |

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 |
|---|---|---|---|
| OPA2333P | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2772IP's 2 µV/°C; higher cost; 360 nA supply current per channel | Better DC stability over temperature; suited for long-duration DC measurements (e.g., weigh scales), not optimized for speed | Select OPA2333P only when ultra-low drift dominates over bandwidth and power constraints |
| LMV722M | Lower bandwidth (10 MHz) but higher slew rate (15 V/µs); 1.2 mA supply current; not rated beyond 105°C | Higher speed for pulse amplification; lacks military-temperature qualification and rail-to-rail output capability | Choose LMV722M for high-speed, non-rail-to-rail applications where extended temperature range is not required |
Compared with OPA2333P and LMV722M, the TLV2772IP uniquely balances rail-to-rail output, 5.1 MHz bandwidth, −55°C to 125°C operation, and 1 mA/channel power - making it optimal for dual-channel analog front-ends in harsh-environment embedded systems.

FAQ
What is the maximum operating temperature range for the TLV2772IP?
The TLV2772IP is specified for operation from −55°C to 125°C, meeting MIL-PRF-38535 Class K and Q-Temp automotive requirements. This rating is validated per the datasheet's "recommended operating conditions" table and applies across the full supply range (2.5 V to 5.5 V). The PDIP-8 package's thermal resistance (θJA = 125°C/W) supports reliable operation at maximum ambient temperature when power dissipation remains below 145 mW.
Does the TLV2772IP support rail-to-rail input voltage range?
No, the TLV2772IP 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 (e.g., 0 V to 3.7 V at VDD = 5 V). This limitation is documented in the "recommended operating conditions" table on page 5 of the SLOS209G datasheet. For true rail-to-rail input, consider TI's TLV2462 or OPA2340 families.
What is the typical input bias current of the TLV2772IP?
The TLV2772IP exhibits a typical input bias current of 2 pA at 25°C, with a maximum of 60 pA across the full −55°C to 125°C temperature range. This value is confirmed in the "electrical characteristics" tables on pages 6 and 8 of the SLOS209G datasheet under test condition VIC = 0, RS = 50 Ω. Such ultra-low bias current enables high-accuracy amplification of high-impedance sources like pH electrodes and piezoelectric sensors.
Can the TLV2772IP drive a 600-Ω load with low distortion?
Yes, the TLV2772IP is specifically characterized for 0.005% THD+N when driving a 600-Ω load at 1 kHz with AV = 1, as stated on page 1 of the datasheet and verified in the "operating characteristics" table on page 9. This performance is enabled by its 10.5 V/µs slew rate and robust output stage, making it suitable for telecom line drivers and audio interface circuits where harmonic distortion must meet ITU-T G.712 specifications.
Is the TLV2772IP pin-compatible with other devices in the TLV277x family?
Yes, the TLV2772IP (PDIP-8) shares identical pinout with TLV2772CD, TLV2772ID, and TLV2772AIP per the "TLV2772 D, DGK, JG, P, OR PW PACKAGE" diagram on page 4 of SLOS209G. All use Pin 1 = IN− (Ch1), Pin 2 = IN+ (Ch1), Pin 3 = OUT (Ch1), Pin 4 = GND, Pin 5 = IN+ (Ch2), Pin 6 = IN− (Ch2), Pin 7 = OUT (Ch2), Pin 8 = VDD. This allows direct substitution within the same package footprint.
