Product details
Overview
TLV2770ID from Texas Instruments is a single-channel, rail-to-rail output CMOS operational amplifier optimized for automotive and industrial applications requiring high-speed precision at low supply voltage. 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 across −40°C to 125°C. It drives 600-Ω loads with 0.005% THD+N and features micropower shutdown (<1 µA).
For engineers reviewing the TLV2770ID datasheet, TLV2770ID pinout, TLV2770ID application, or TLV2770ID equivalent, key selection criteria include its extended temperature range (−40°C to 125°C), rail-to-rail output swing into 600-Ω, low-noise (17 nV/√Hz) performance at 5 V, and integrated shutdown functionality in an 8-pin MSOP package.
Technical Context
The TLV2770ID employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, enabling high-impedance sensor interfacing and low-distortion signal conditioning. Its unity-gain-stable architecture supports 5.1 MHz bandwidth while maintaining 46° phase margin into 600-Ω + 100 pF loads.
It integrates a dedicated shutdown terminal (Pin 5) that reduces supply current to <1 µA while preserving rail-to-rail output capability upon wake-up. The device is characterized at both 2.7 V and 5 V, with guaranteed operation over the full −40°C to 125°C automotive temperature range.
Key Specifications

| Gain-Bandwidth Product | 5.1 MHz typ - supports stable closed-loop gains ≥2 at frequencies up to 2.5 MHz. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.36 mV DC error in precision gain stages without trimming. |
| Supply Current (Active) | 1 mA per channel - allows battery-powered designs with >1000-hour runtime on a 1000 mAh cell. |
| Shutdown Current | <1 µA - reduces system standby power by >1000× versus active mode. |
| Input Noise Voltage | 17 nV/√Hz at 10 kHz - maintains SNR >95 dB for 20 kHz audio band amplification. |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom line-driver distortion requirements. |
Pinout & Package
TLV2770ID is packaged in an 8-pin MSOP (DGK) with exposed thermal pad. This thermally enhanced package supports 424 mW power dissipation at 25°C with 3.4 mW/°C derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected; must be left floating or tied to GND for mechanical stability. |
| 2 | Inverting Input (IN−) | Differential input node; 2 pA bias current enables high-Z source interfacing. |
| 3 | Non-Inverting Input (IN+) | Differential input node; common-mode range extends to rail (GND to VDD −1.3 V). |
| 4 | Ground (GND) | Analog and digital reference return; requires low-impedance connection to PCB ground plane. |
| 5 | Shutdown (SHDN) | Active-high control; pulls supply current to <1 µA when driven ≥1.4 V (VDD = 5 V). |
| 6 | Positive Supply (VDD) | Single supply input; operates from 2.5 V to 5.5 V; bypass with 0.1 µF ceramic near pin. |
| 7 | Output (OUT) | Rail-to-rail output capable of sourcing/sinking ±2.2 mA into 600 Ω while maintaining linearity. |
| 8 | No Connect (NC) | Internally unconnected; must be left floating or tied to GND for mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|

| Low THD+N into 600 Ω | 0.005% at 1 kHz supports analog transmission in telecom line interfaces without external filtering. |
| Extended temperature range | Specified from −40°C to 125°C meets AEC-Q100 Grade 2 requirements for under-hood automotive electronics. |
| High CMRR & PSRR | 84 dB CMRR and 89 dB PSRR minimize error from noisy power rails or common-mode interference in motor control feedback paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2770CD | Same electrical specs but rated for 0°C to 70°C only; no automotive qualification. | Limited to commercial-grade systems without thermal stress or reliability certification needs. | Select TLV2770CD only for cost-sensitive consumer applications where ambient temperature stays below 70°C. |
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV/°C drift vs. TLV2770ID's 2 µV/°C; higher 17 µV VIO max but superior long-term stability. | Better for ultra-low-drift DC-coupled sensors (e.g., strain gauges); lower bandwidth (350 kHz) limits AC response. | Choose OPA333AIDBVR when DC accuracy over temperature and time outweighs need for 5.1 MHz bandwidth or 10.5 V/µs slew rate. |
Compared with TLV2770CD, TLV2770ID adds −40°C to 125°C operation and AEC-Q100 alignment; compared with OPA333AIDBVR, it trades zero-drift stability for 14× higher bandwidth and 30× faster slew rate-making TLV2770ID optimal for mixed-signal systems needing speed, precision, and automotive robustness.

FAQ
What is the operating temperature range for TLV2770ID?
The TLV2770ID is specified for continuous operation from −40°C to 125°C, meeting automotive Grade 2 requirements. This range is validated across all key parameters including input offset voltage, supply current, and output drive capability-ensuring reliable performance in under-hood and industrial control environments where ambient temperatures exceed 100°C.
Does TLV2770ID support true rail-to-rail input?
No, TLV2770ID features rail-to-rail *output* swing only. Its common-mode input voltage range extends from GND to VDD −1.3 V at 5 V supply (or GND to VDD −1.35 V at 2.7 V), meaning the inverting and non-inverting inputs cannot accept signals within ~1.3 V of VDD. This limitation is clearly documented in the "Recommended Operating Conditions" table of the SLOS209G datasheet.
What is the typical shutdown wake-up time for TLV2770ID?
The TLV2770ID has a typical amplifier turn-on time (t(ON)) of 1.2 µs when transitioning from shutdown to active mode at VDD = 5 V and AV = 5, measured to the 50% point of output step response. This fast wake-up enables efficient duty-cycled operation in battery-powered sensor nodes without introducing significant latency during acquisition windows.
Can TLV2770ID drive a 600-Ω load with low distortion at 5 V supply?
Yes, TLV2770ID delivers 0.005% THD+N into a 600-Ω load at 1 kHz with AV = 1 and VDD = 5 V, as confirmed in the "Operating Characteristics" table (page 9) of the SLOS209G datasheet. This performance meets stringent telecom line-driver specifications and enables direct interface with legacy analog telephone infrastructure without external buffering.
Is TLV2770ID pin-compatible with other devices in the TLV277x family?
TLV2770ID shares the same 8-pin MSOP (DGK) pinout with TLV2770CD, TLV2770AID, and TLV2770IP, making it drop-in replaceable within the single-channel TLV2770 variant group. However, it is *not* pin-compatible with dual-channel TLV2772 or quad-channel TLV2774 devices, which use different pin assignments for multiple amplifiers and shared shutdown functions.
