Product details
Overview
TLV2770CD from Texas Instruments is a single-channel CMOS rail-to-rail output operational amplifier optimized for precision, low-power, and high-speed signal conditioning in 2.5 V to 5.5 V single-supply systems. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, 17 nV/√Hz input noise, and micropower shutdown (<1 µA), making it suitable for driving ADC reference inputs and portable sensor front-ends.
For engineers reviewing the TLV2770CD datasheet, TLV2770CD pinout, TLV2770CD application, or TLV2770CD equivalent, this page provides verified package mapping (SOIC-8), confirmed rail-to-rail output behavior, validated shutdown functionality, and real-world design context for battery-powered instrumentation and automotive-grade signal chains.
Technical Context
The TLV2770CD employs a CMOS input stage with 2 pA typical input bias current and operates across 0°C to 70°C ambient temperature. Its architecture supports unity-gain stable operation with 46° phase margin into 600 Ω loads and 100 pF capacitive loads, enabling direct drive of analog-to-digital converter inputs without external buffering.
It features an integrated micropower shutdown control (pin 5) that reduces supply current to <1 µA while maintaining fast turnon/turnoff times (1.2 µs / 335 ns), and its rail-to-rail output swing (within 100 mV of rails at 2.2 mA load) ensures maximum dynamic range in low-voltage data acquisition systems.
Key Specifications

| 2 | Inverting Input (IN−) | Differential input node with 1012 Ω input resistance and 8 pF common-mode capacitance |
| 3 | Noninverting Input (IN+) | Differential input node; bias current 2 pA enables high-impedance sensor interfacing |
| 4 | GND | Analog ground reference; requires low-impedance connection to PCB ground plane |
| 5 | Shutdown (SHDN) | Active-high digital control; pulls supply current to <1 µA when logic low (≤0.8 V) |
| 6 | VDD | Positive supply rail; accepts 2.5 V to 5.5 V with 7 V absolute maximum rating |
| 7 | Output (OUT) | Capable of sourcing/sinking ±2.2 mA while maintaining rail-to-rail swing |
| 8 | NC (No internal connection) | Unbonded pad - no electrical function; may be used as thermal pad anchor if soldered |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDR | Zero-drift architecture; 0.1 µV/°C offset drift vs. TLV2770CD's 2 µV/°C; higher cost; 17 µA supply current | Better for ultra-stable DC-coupled sensors (e.g., strain gauges); less suitable for AC-coupled high-speed signal paths | Choose OPA333AIDR when long-term DC accuracy dominates over power and speed requirements. |
| MCP6001T-E/OT | Lower slew rate (0.6 V/µs); no shutdown pin; 100 µA supply current; wider VDD range (1.8–6.0 V) | Targeted at ultra-low-power always-on monitoring; lacks rail-to-rail output swing at high load currents | Choose MCP6001T-E/OT only for non-critical, low-bandwidth, always-on applications where shutdown is unnecessary. |
Compared with OPA333AIDR and MCP6001T-E/OT, TLV2770CD uniquely balances high-speed performance (10.5 V/µs), micropower shutdown (<1 µA), and rail-to-rail output in a cost-effective SOIC-8 package-making it optimal for portable instrumentation requiring both precision and responsiveness.

FAQ
What is the operating supply voltage range for TLV2770CD?
The TLV2770CD operates from a single supply of 2.5 V to 5.5 V, with absolute maximum rating of 7 V. It is fully characterized at 2.7 V and 5 V, and maintains rail-to-rail output swing and 10.5 V/µs slew rate across this range-enabling direct use in 3.3 V and 5 V systems without level translation.
Does TLV2770CD support rail-to-rail input capability?
No, TLV2770CD features rail-to-rail *output* only. Its common-mode input voltage range extends from GND to VDD − 1.3 V (e.g., 0 V to 3.7 V at 5 V supply), meaning it cannot accept signals at the positive rail. Input stage is CMOS-based with 2 pA bias current, optimized for high-impedance sources within this defined VICR.
How does the shutdown pin (pin 5) function on TLV2770CD?
Pin 5 is an active-high shutdown control: applying ≥2.0 V (VIH) disables the amplifier and reduces supply current to <1 µA, while ≤0.8 V (VIL) enables normal operation. The device achieves 1.2 µs turnon time and 335 ns turnoff time, supporting rapid power cycling in duty-cycled sensor systems without compromising signal integrity.
Is TLV2770CD suitable for driving 600-Ω loads with low distortion?
Yes-TLV2770CD is explicitly characterized for 0.005% THD+N into 600 Ω at 1 kHz with AV = 1, confirming suitability for telecom line drivers and professional audio interfaces. Its 2.2 mA output drive capability and 46° phase margin ensure stable operation without external compensation when directly loaded.
What is the input offset voltage specification for TLV2770CD over temperature?
TLV2770CD has a maximum input offset voltage of 2.7 mV over the full 0°C to 70°C operating range, with a typical value of 360 µV at 25°C and a temperature coefficient of 2 µV/°C. This ensures predictable, bounded DC error in precision gain stages without requiring frequent recalibration.
