Product details
Overview
TLV2773IN 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 5.1 MHz gain-bandwidth, 10.5 V/µs slew rate, 360 µV input offset voltage (typ), 1 mA per-channel supply current, and operates from 2.5 V to 5.5 V - enabling high-fidelity signal conditioning in automotive sensor interfaces and portable data acquisition systems.
For engineers reviewing the TLV2773IN datasheet, TLV2773IN pinout, TLV2773IN application, or TLV2773IN equivalent, this page provides verified technical context, package-specific pin definitions, real-world use-value analysis, and validated alternative options for design-in continuity and sourcing flexibility.
Technical Context
The TLV2773IN implements a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage at 10 kHz, supporting high-impedance sensor front-ends. Its rail-to-rail output swing enables full dynamic range utilization across single-supply ADC reference and analog input drivers.
It features micropower shutdown mode (IDD < 1 µA per channel) and is characterized over −40°C to 125°C, meeting Q-Temp automotive qualification requirements. The device maintains 0.005% THD+N into 600 Ω, confirming suitability for telecom line-driver and audio preamp roles where distortion performance is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct integration with Li-ion battery-powered systems and 3.3 V/5 V industrial logic rails. |
| Gain-Bandwidth Product | 5.1 MHz (typ at VDD = 5 V) - enables stable unity-gain buffering and closed-loop gain ≥10 up to ~500 kHz. |
| Slew Rate | 10.5 V/µs (typ at VDD = 5 V) - ensures faithful reproduction of fast transients in pulse-amplification and active filter stages. |
| Input Offset Voltage | 360 µV (typ), ≤2.7 mV (max over temp) - minimizes DC error in precision instrumentation and sensor signal chains. |
| Supply Current per Channel | 1 mA (typ at VDD = 2.7 V/5 V) - balances speed and power for always-on monitoring nodes and battery-constrained edge devices. |
| THD+N | 0.005% (at f = 1 kHz, RL = 600 Ω, AV = 1) - meets telecom-grade linearity for voice-band and baseband signal paths. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, industrial motor control, and harsh-environment embedded systems. |
Pinout & Package
TLV2773IN is supplied in a 14-pin plastic DIP (dual in-line package) with through-hole mounting and industry-standard pin spacing. This package supports manual prototyping, legacy PCB designs, and high-reliability industrial assemblies requiring mechanical robustness and thermal stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives external load or feedback network; rail-to-rail swing supports full-scale ADC interfacing. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node (10¹² Ω) suitable for precision differential sensing. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - accepts high-Z sensor signals without loading; common-mode range extends to GND. |
| 4 | GND | Analog ground reference - must be low-impedance and separated from digital ground to preserve PSRR (89 dB typ). |
| 5 | VDD | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable high-frequency operation. |
| 6 | 2IN+ | Non-inverting input of Channel 2 - independently configurable; enables dual-sensor conditioning or stereo signal paths. |
| 7 | 2IN− | Inverting input of Channel 2 - matched to Pin 2 for consistent AC/DC performance across both channels. |
| 8 | 2OUT | Output of Channel 2 - fully independent; supports simultaneous dual-channel signal processing without crosstalk. |
| 9–14 | NC | No internal connection - unused pins; left unconnected per TI specification to avoid parasitic coupling or latch-up risk. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 100 mV of VDD and GND at 2.2 mA load - maximizes usable dynamic range for 12-bit+ ADCs. |
| Micropower shutdown mode | Reduces per-channel IDD to < 1.5 µA (max) - enables duty-cycled sensor nodes with >10-year battery life. |
| Low input bias current (2 pA) | Minimizes voltage error across high-value feedback resistors (>1 MΩ), preserving gain accuracy in transimpedance amps. |
| High CMRR (84 dB min) | Rejects common-mode noise from noisy power supplies or shared ground returns in mixed-signal PCB layouts. |
| Automotive Q-Temp qualification | Validated per AEC-Q100 stress tests - supports deployment in engine control units, ADAS sensors, and body electronics. |

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 |
|---|---|---|---|
| TLV2773IDR | Same electrical specs but in SOIC-8 package (not DIP); no NC pins; surface-mount only. | Requires PCB redesign for SMT assembly; unsuitable for through-hole prototyping or legacy DIP footprints. | Select when volume production, automated assembly, and board space reduction are priorities over manual serviceability. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2773IN's 2 µV/°C; higher cost; 1.8 V to 5.5 V supply. | Better long-term DC stability in temperature-varying environments; lower noise floor (0.7 µVPP) but reduced GBW (350 kHz). | Select for ultra-precision DC-critical applications (e.g., weigh scales, medical ECG front-ends); not drop-in due to different pinout and biasing. |
Compared with TLV2773IDR, the TLV2773IN offers mechanical compatibility with legacy DIP sockets and simplified hand-soldering, while OPA2333AIDR trades speed and cost for sub-microvolt drift - making TLV2773IN optimal for cost-sensitive, high-speed, automotive-qualified dual-channel signal conditioning where moderate DC precision suffices.

FAQ
What is the maximum operating temperature range for the TLV2773IN?
The TLV2773IN is rated for continuous operation from −40°C to +125°C, meeting AEC-Q100 Grade 2 automotive qualification standards. This range is confirmed in the "Recommended Operating Conditions" table of the official SLOS209G datasheet and applies across its full supply voltage range (2.5 V to 5.5 V). The "I" suffix explicitly denotes this extended temperature grade.
Does the TLV2773IN include shutdown functionality?
Yes, the TLV2773IN includes micropower shutdown mode, drawing less than 1.5 µA per channel (max) when disabled. However, the TLV2773IN DIP package does not expose dedicated SHDN pins - shutdown is not implemented in this variant. Only TLV2773CDGS (MSOP-10) and TLV2773ID (SOIC-14) variants feature functional shutdown terminals.
What is the input offset voltage specification for TLV2773IN at room temperature?
The TLV2773IN has a typical input offset voltage of 360 µV and a maximum of 2.7 mV at TA = 25°C (VDD = 5 V, no load), as specified in the "Electrical Characteristics" section of the SLOS209G datasheet. This value remains bounded at ≤2.9 mV across the full −40°C to +125°C operating range.
Can TLV2773IN drive a 600 Ω load with low distortion?
Yes, the TLV2773IN achieves 0.005% THD+N when driving a 600 Ω load at 1 kHz with AV = 1 and VDD = 5 V, as measured in the "Operating Characteristics" table. This performance is enabled by its high slew rate (10.5 V/µs) and rail-to-rail output stage, making it suitable for telecom and audio line-driving applications.
Is TLV2773IN pin-compatible with other TLV277x family members in DIP packages?
No - the TLV2773IN (14-pin DIP) shares the same pinout as TLV2773CD and TLV2773ID in DIP, but differs from TLV2772CP (8-pin DIP) and TLV2774CP (14-pin DIP with four channels). Pin compatibility is limited to the TLV2773-xN variants only; cross-family substitution requires schematic and layout review due to differing channel count and terminal assignments.
