Product details
Overview
TLV2770IDGK from Texas Instruments is a single-channel CMOS rail-to-rail output operational amplifier optimized for low-voltage, high-speed signal conditioning in automotive and industrial systems. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, 1 mA supply current per channel, and operates from 2.5 V to 5.5 V - enabling precision analog front-end design in ADC driver and sensor interface applications.
For engineers reviewing the TLV2770IDGK datasheet, TLV2770IDGK pinout, TLV2770IDGK application, or TLV2770IDGK equivalent, this page provides verified technical context, package-specific pin mapping, real-world application use cases, and validated alternative options for design-in and sourcing decisions.
Technical Context
The TLV2770IDGK employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage at 10 kHz, supporting high-impedance sensor interfacing. Its rail-to-rail output swing (within 100 mV of rails at 2.2 mA load) and micropower shutdown mode (<1 µA) enable operation in battery-powered and space-constrained systems.
Characterized across −40°C to +125°C, it meets automotive-grade reliability requirements with Q-Temp qualification. The device features 0.005% THD+N driving 600 Ω, making it suitable for telecom line drivers and precision instrumentation where distortion and thermal stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical - enables fast settling for 12-bit ADC sampling at ≥1 MSPS without slewing-induced distortion. |
| Gain-Bandwidth Product | 5.1 MHz typical - supports stable unity-gain buffer configurations up to ~5 MHz with adequate phase margin. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.01% full-scale error in 3.3 V-range 12-bit systems without trimming. |
| Supply Current | 1 mA per channel - allows dual-channel operation within 2 mA budget for portable sensor nodes. |
| Rail-to-Rail Output | Swings to within 100 mV of VDD/GND at 2.2 mA - maximizes dynamic range when driving SAR ADC reference inputs. |
| Shutdown Current | <1 µA - reduces standby power by >99.9% during system sleep cycles in automotive body control modules. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive applications per AEC-Q100 stress test requirements. |
Pinout & Package
TLV2770IDGK is housed in an 8-pin MSOP (DGK) package with 0.65 mm pitch, 3.0 mm × 3.0 mm footprint, and exposed thermal pad (not electrically connected). This thermally enhanced package supports continuous operation at 125°C ambient with appropriate PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left floating or tied to GND for mechanical stability; no electrical function. |
| 2 | IN− | Inverting input - high-impedance CMOS node; requires matched trace routing to minimize common-mode rejection degradation. |
| 3 | IN+ | Non-inverting input - 2 pA bias current enables direct connection to high-Z sources like thermocouples or pH electrodes. |
| 4 | GND | Analog ground reference - must connect to clean, low-impedance ground plane; separate from digital ground if mixed-signal layout. |
| 5 | SHDN | Active-low shutdown control - pulls to GND to enter <1 µA state; requires external pull-up for normal operation. |
| 6 | VDD | Positive supply - accepts 2.5 V to 5.5 V; decoupling capacitor (100 nF X7R) required within 3 mm of pin. |
| 7 | OUT | Amplifier output - rail-to-rail capable; drives 600 Ω loads with 0.005% THD+N at 1 kHz for telecom line interface. |
| 8 | NC | No internal connection - same as Pin 1; no routing or connection required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full 2.5 V–5.5 V output range into 2.2 mA loads - eliminates need for level-shifting in single-supply data acquisition. |
| Micropower shutdown mode | Reduces IDD to <1 µA - enables duty-cycled sensor monitoring in automotive tire pressure sensors with multi-year battery life. |
| Low THD+N (0.005%) | Meets Class D audio preamp and telecom line driver specs - avoids harmonic interference in shared analog/digital PCBs. |
| Extended temperature range | Specified from −40°C to +125°C - supports placement near engine control units without derating or heatsinking. |
| High slew rate + bandwidth | 10.5 V/µs / 5.1 MHz combo enables accurate pulse amplification in ultrasonic flow meter front-ends. |

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 |
|---|---|---|---|
| TLV2770CDGK | Same architecture and pinout, but rated for 0°C to 70°C only; 2.5 mV max VIO vs. 2.7 mV for TLV2770IDGK. | Limited to commercial-temperature consumer or lab equipment; not qualified for automotive under-hood use. | Select TLV2770CDGK only for cost-sensitive, non-automotive designs where extended temperature range is unnecessary. |
| OPA333AIDBVR | Zero-drift architecture; 10 µV max VIO, 0.1 µV/°C drift, but lower 350 kHz GBW and 0.16 V/µs slew rate. | Better DC precision for weigh scales or thermopile amplifiers; unsuitable for high-frequency ADC buffering or line drivers. | Choose OPA333AIDBVR when ultra-low offset and drift dominate over speed; avoid when >1 MHz bandwidth or >1 V/µs slew is required. |
Compared with TLV2770CDGK, TLV2770IDGK adds automotive temperature qualification and tighter VIO spec over full range; compared with OPA333AIDBVR, it trades DC precision for 15× higher slew rate and 14× greater bandwidth - making it optimal for dynamic signal paths rather than static measurements.

FAQ
What is the maximum operating temperature range for TLV2770IDGK?
The TLV2770IDGK is fully specified and qualified for continuous operation from −40°C to +125°C ambient temperature. This extended range is validated per AEC-Q100 stress testing protocols and supports placement in demanding automotive under-hood locations such as engine control units and transmission control modules without thermal derating.
Does TLV2770IDGK support true rail-to-rail input capability?
No, TLV2770IDGK features rail-to-rail *output* only. Its input common-mode voltage range extends from GND to VDD − 1.3 V (e.g., 0 V to 4.2 V at VDD = 5.5 V), meaning the inverting and non-inverting inputs cannot accept signals within 1.3 V of the positive rail. Input stage headroom must be accounted for in level-shifting or biasing networks.
How does the shutdown pin (Pin 5) function on TLV2770IDGK?
Pin 5 (SHDN) is an active-low digital control input. When pulled to GND, the amplifier enters micropower shutdown with supply current dropping below 1 µA. When left open or pulled high (≥1.8 V), the device operates normally. A 100 kΩ pull-up resistor to VDD is recommended for robust default-on behavior in noisy automotive environments.
Can TLV2770IDGK drive a 600 Ω load while maintaining low distortion?
Yes - the TLV2770IDGK delivers 0.005% THD+N when driving a 600 Ω load at 1 kHz with AV = 1, meeting ITU-T G.712 line driver specifications. At higher frequencies or gains, THD+N increases predictably (e.g., 0.016% at AV = 10), remaining well below 0.1% up to 100 kHz, confirming suitability for voiceband and broadband analog interfaces.
What is the typical input bias current of TLV2770IDGK and why does it matter?
The TLV2770IDGK has a typical input bias current of 2 pA, with a maximum of 60 pA over temperature. This ultra-low value minimizes voltage errors across high-impedance source impedances (e.g., >1 MΩ), making it ideal for pH probes, piezoelectric sensors, and photodiode transimpedance stages where leakage-induced offset would otherwise dominate measurement accuracy.
