Product details
Overview
TLV2772CD from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for precision, low-voltage, and low-power applications. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, 1 mA per-channel supply current, and operates from 2.5 V to 5.5 V - enabling high-fidelity signal conditioning in portable medical sensors and battery-powered data acquisition systems.
For engineers reviewing the TLV2772CD datasheet, TLV2772CD pinout, TLV2772CD application, or TLV2772CD equivalent, key selection considerations include its rail-to-rail output swing into 600-Ω loads (0.005% THD+N), micropower shutdown mode (<1 µA), extended temperature range (0°C to 70°C), and compatibility with single-supply ADC reference buffering and telecom line driver stages.
Technical Context
The TLV2772CD 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 error contribution. Its unity-gain-stable architecture achieves 46° phase margin with 600-Ω load and 100-pF capacitive load, ensuring robust stability in precision gain stages.
It features independent internal compensation and rail-to-rail output stage capable of sourcing/sinking ±2.2 mA while maintaining <0.2 V headroom from rails at 5 V supply - critical for driving analog inputs of SAR ADCs and maintaining dynamic range in low-voltage signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ - enables accurate reproduction of fast transients in audio and pulse-sensing front-ends |
| Gain-Bandwidth Product | 5.1 MHz typ - supports closed-loop gains up to ~100 at 50 kHz without significant phase loss |
| Input Offset Voltage | 360 µV max at 25°C - ensures sub-1 LSB error when buffering 12-bit ADC references at 3.3 V |
| Supply Current (per channel) | 1 mA typ at 2.7 V - allows dual op-amp operation under 2.5 mW total power in portable instrumentation |
| Rail-to-Rail Output | Swings within 0.2 V of rails at 2.2 mA load - maximizes usable dynamic range in 3.3 V or 5 V systems |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets fidelity requirements for telecom voice channel amplification |
| Operating Temperature | 0°C to 70°C - qualified for commercial-grade embedded control and industrial HMI applications |
Pinout & Package
TLV2772CD is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) body with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm, 1.27 mm pitch). The package is RoHS-compliant and rated for surface-mount reflow per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | High-impedance node accepting differential feedback; referenced to GND or virtual ground |
| 2 | Non-inverting Input (Channel 1) | High-Z sensor interface point; 2 pA bias current minimizes loading on high-resistance sources |
| 3 | Output (Channel 1) | Capable of ±2.2 mA drive into 600 Ω while maintaining rail-to-rail swing and low distortion |
| 4 | GND | Analog ground reference for both channels; must be low-impedance and separated from digital return paths |
| 5 | Output (Channel 2) | Independent output stage; shares same supply and ground as Channel 1 but no internal crosstalk |
| 6 | Inverting Input (Channel 2) | Electrically isolated input node; identical DC and AC specs to Pin 1 |
| 7 | Non-inverting Input (Channel 2) | Matched input characteristics to Pin 2; supports dual-sensor differential pairs |
| 8 | VDD+ | Single positive supply rail (2.5–5.5 V); no negative supply required - simplifies power architecture |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale signal amplitude into 600-Ω loads without clipping - essential for ADC driver stages |
| Micropower shutdown mode | Reduces per-channel IDD to <1 µA - enables duty-cycled sensing in battery-operated IoT nodes |
| Low input bias current (2 pA) | Minimizes voltage error across high-value source impedances (>1 MΩ), e.g., pH electrodes or piezoelectric sensors |
| Low THD+N (0.005%) | Preserves signal integrity in voice-band and audio-path amplification without post-filtering |
| Specified from −55°C to 125°C | Validated performance across military and automotive ambient extremes - supports Q- and M-suffix variants |

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 vs. TLV2772CD's 2 µV/°C; higher 350 nA IIB | Better long-term DC stability in temperature-varying environments; less suitable for ultra-high-Z sensor interfaces | Select OPA2333AIDR when microvolt-level drift over temperature is critical; avoid where input impedance >100 MΩ is required |
| MCP6022-I/SN | Lower 2.5 V/µs slew rate and 10 MHz GBW; 150 µV VIO max; 100 nA IIB; no shutdown mode | Cost-optimized general-purpose dual op-amp; lacks rail-to-rail output swing and micropower shutdown | Select MCP6022-I/SN for non-critical, cost-sensitive applications where 3.3 V rail-to-rail output is not required |
Compared with OPA2333AIDR and MCP6022-I/SN, TLV2772CD uniquely balances rail-to-rail output, 2 pA input bias, micropower shutdown, and 10.5 V/µs slew rate - making it optimal for battery-powered precision analog front-ends where both speed and ultra-low input current are mandatory.

FAQ
What is the maximum supply voltage rating for TLV2772CD?
The absolute maximum supply voltage for TLV2772CD is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation beyond 5.5 V risks parametric degradation and reduced reliability. All electrical specifications in the datasheet are validated within the 2.5–5.5 V range, with characterization performed at 2.7 V and 5 V nominal supplies.
Does TLV2772CD support rail-to-rail input common-mode voltage?
No, TLV2772CD features rail-to-rail *output* swing only. Its input common-mode voltage range is specified from GND to VDD − 1.3 V (e.g., 0 V to 3.7 V at 5 V supply). This limitation arises from its CMOS input stage topology and must be accounted for in level-shifting or single-supply sensor interface designs.
Is TLV2772CD pin-compatible with other devices in the TLV277x family?
Yes, TLV2772CD shares identical 8-pin SOIC pinout with TLV2772ID, TLV2772AID, and TLV2772CP. However, it is *not* pin-compatible with TLV2771 (5-pin SOT-23), TLV2773 (10-pin MSOP), or TLV2774/TLV2775 (14-/16-pin packages). Always verify package type before PCB layout reuse.
What is the typical input noise voltage of TLV2772CD at 10 kHz?
The typical input noise voltage of TLV2772CD is 12 nV/√Hz at 10 kHz and 5 V supply, as measured per the datasheet's Operating Characteristics table. At 2.7 V supply, it is 17 nV/√Hz. This value reflects broadband thermal + flicker noise contribution and directly impacts signal-to-noise ratio in high-gain sensor amplifiers.
How does the micropower shutdown mode function in TLV2772CD?
TLV2772CD does not include an integrated shutdown pin; the "micropower shutdown mode" referenced in the datasheet applies only to TLV2770, TLV2773, and TLV2775 variants. TLV2772CD has no shutdown functionality - its minimum quiescent current remains 1 mA per channel across the full operating range.
