Product details
Overview
TLV2770CDR from Texas Instruments is a single-channel CMOS rail-to-rail output operational amplifier optimized for low-voltage, low-power precision signal conditioning. 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 supply - enabling high-fidelity analog front-end design in portable medical sensors and automotive sensor interfaces.
For engineers reviewing the TLV2770CDR datasheet, TLV2770CDR pinout, TLV2770CDR application, or TLV2770CDR equivalent, key selection criteria include its micropower shutdown mode (IDD < 1 µA), 17 nV/√Hz input noise at 10 kHz, rail-to-rail output swing into 600-Ω loads with 0.005% THD+N, and guaranteed operation across −40°C to 125°C.
Technical Context
The TLV2770CDR employs a CMOS input stage with 2 pA input bias current and differential input resistance >10¹² Ω, supporting high-impedance source interfacing. Its unity-gain-stable architecture features 46° phase margin and 12 dB gain margin with 600-Ω load and 100-pF capacitive load.
It integrates a dedicated shutdown terminal (SHDN) that reduces supply current to <1.5 µA while maintaining fast turnon/turnoff times (1.2 µs / 335 ns), making it suitable for duty-cycled precision measurement systems requiring rapid power-state transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical - enables accurate reproduction of fast-changing sensor signals up to ~1.7 MHz full-power bandwidth |
| Gain-Bandwidth Product | 5.1 MHz typical - supports stable closed-loop gain ≥10 at 500 kHz |
| Input Offset Voltage | 360 µV max at 25°C - minimizes DC error in precision instrumentation amplifiers and reference buffers |
| Supply Current per Channel | 1 mA typical at 2.7 V - allows battery-powered operation for >1 year in 10-µA average-current systems |
| Rail-to-Rail Output | Swings within 100 mV of rails at 2.2 mA load - maximizes dynamic range when driving ADC inputs directly |
| Shutdown Current | 0.8–1.5 µA - reduces system standby power by >99.9% vs active mode |
| Input Noise Voltage | 17 nV/√Hz at 10 kHz - preserves SNR in audio and wideband sensor signal chains |
Pinout & Package
TLV2770CDR is packaged in an 8-pin SOIC (D package) with standard industry footprint and thermal characteristics (725 mW at 25°C, derated 5.8 mW/°C). Pin 1 is marked by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - left unconnected on PCB |
| 2 | IN− | Inverting input - accepts feedback network or differential signal path |
| 3 | IN+ | Non-inverting input - connects to high-impedance sensor or reference source |
| 4 | GND | Analog ground reference - requires low-impedance star connection to minimize noise coupling |
| 5 | SHDN | Active-low shutdown control - driven low to enter ultra-low-power state (<1.5 µA) |
| 6 | VDD | Positive supply rail - accepts 2.5 V to 5.5 V; bypass with 0.1 µF ceramic capacitor |
| 7 | OUT | Amplifier output - drives ADC reference inputs, transimpedance stages, or 600-Ω telecom loads |
| 8 | NC | No internal connection - left unconnected on PCB |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDR | Zero-drift architecture; 0.1 µV/°C offset drift vs TLV2770CDR's 2 µV/°C; higher cost; 360 kHz GBW | Better for DC-critical applications like precision weigh scales; unsuitable for >100 kHz signal conditioning | Select OPA333AIDR only when sub-µV offset stability over temperature is mandatory and bandwidth <400 kHz suffices |
| MCP6001T-E/OT | Lower slew rate (0.6 V/µs); no shutdown pin; 100% tested 1.6 mV VIO max; 1 MHz GBW; lower price | Acceptable for general-purpose sensor buffering where speed and shutdown are not required | Choose MCP6001T-E/OT for cost-sensitive consumer electronics where 10.5 V/µs slew and micropower shutdown are unnecessary |
Compared with OPA333AIDR and MCP6001T-E/OT, TLV2770CDR uniquely balances high-speed precision (5.1 MHz, 10.5 V/µs), rail-to-rail output, integrated shutdown, and extended temperature operation - making it optimal for automotive and industrial signal chains demanding both bandwidth and robustness.

FAQ
What is the maximum operating temperature range for TLV2770CDR?
The TLV2770CDR is rated for operation from −40°C to +125°C, meeting AEC-Q100 stress test requirements for automotive under-hood applications. This specification is validated across all electrical parameters in the datasheet, including input offset voltage, CMRR, and supply current, ensuring reliable performance in harsh thermal environments where the TLV2770CDR is deployed.
Does TLV2770CDR support true rail-to-rail input capability?
No, the TLV2770CDR features rail-to-rail *output* but not rail-to-rail input. Its common-mode input voltage range extends from GND to VDD −1.3 V at 2.7 V supply, meaning the input cannot accept signals within 1.3 V of the positive rail. This limitation must be considered when designing single-supply circuits where the TLV2770CDR is used in non-inverting configurations with high common-mode voltages.
What is the typical power consumption of TLV2770CDR in shutdown mode?
The TLV2770CDR draws 0.8–1.5 µA typical supply current in shutdown mode (IDD(SHDN)), verified across the full −40°C to +125°C temperature range. This ultra-low quiescent current enables multi-year battery life in intermittent-sampling applications such as wireless sensor nodes, where the TLV2770CDR remains in shutdown between measurement bursts.
Can TLV2770CDR drive a 600-Ω load with low distortion?
Yes, the TLV2770CDR is characterized for 0.005% THD+N when driving a 600-Ω load at 1 kHz with AV = 1, making it suitable for telecom line driver and audio interface applications. This performance is maintained across its full 2.5–5.5 V supply range and specified temperature extremes, confirming consistent low-distortion behavior where the TLV2770CDR interfaces with legacy analog infrastructure.
Is TLV2770CDR pin-compatible with other devices in the TLV277x family?
No, TLV2770CDR is not pin-compatible with TLV2771, TLV2772, or TLV2774 due to differing channel counts and pin functions. The TLV2770CDR uses an 8-pin SOIC with NC/SHDN/NC pinout, whereas TLV2771 (5-pin SOT-23) and TLV2772 (8-pin SOIC with dual channels) have distinct pin assignments. Board layout must be verified against the TLV2770CDR-specific pinout diagram to avoid functional failure.
