Product details
Overview
TLV2773AIN from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for automotive and industrial applications. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, 1 mA per-channel supply current, and operates from 2.5 V to 5.5 V single supply - enabling high-fidelity signal conditioning in ADC driver and sensor front-end circuits across −40°C to 125°C.
For engineers reviewing the TLV2773AIN datasheet, TLV2773AIN pinout, TLV2773AIN application, or TLV2773AIN equivalent, this device is selected for precision analog signal paths requiring low distortion (0.005% THD+N into 600 Ω), micropower shutdown (<1 µA), and extended temperature reliability in automotive ECUs and industrial data acquisition systems.
Technical Context
The TLV2773AIN uses a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, supporting high-impedance sensor interfacing. Its rail-to-rail output stage drives loads down to 600 Ω while maintaining 0.005% THD+N at 1 kHz - critical for telecom line drivers and audio preamplifiers.
It integrates independent shutdown controls per channel (1SHDN, 2SHDN), enabling dynamic power management in multi-stage analog chains. The device is characterized across −40°C to 125°C and qualified to automotive AEC-Q100 standards, with input offset voltage specified at ≤2.2 mV over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical - enables accurate reproduction of fast-changing signals up to ~1.7 MHz full-power bandwidth into 10 kΩ. |
| Gain-Bandwidth Product | 5.1 MHz typical - supports stable unity-gain and closed-loop gains ≥2 with phase margin ≥46° into 600 Ω. |
| Input Offset Voltage | ≤2.2 mV max over −40°C to 125°C - ensures <0.1% error in 2.5 V reference buffer or 12-bit ADC front-end applications. |
| Supply Current (per channel) | 1 mA typical at 2.7 V - allows dual op-amp operation within 2 mA total, suitable for battery-powered sensor nodes. |
| Shutdown Current | <1.5 µA per channel - reduces system standby power by >99.8% when channels are disabled. |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom-grade line driver requirements without external filtering. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
TLV2773AIN is packaged in a 14-pin plastic DIP (N package) with through-hole mounting and industry-standard pin spacing. This package provides mechanical robustness and thermal stability for high-reliability automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Channel 1 output - rail-to-rail swing supports direct interface to SAR ADC reference inputs. |
| 2 | 1IN− | Inverting input - high-impedance CMOS node (10¹² Ω) minimizes loading on precision voltage dividers. |
| 3 | 1IN+ | Non-inverting input - matched to Pin 2 for optimal common-mode rejection in differential configurations. |
| 4 | VDD | Positive supply - accepts 2.5 V to 5.5 V; decoupling capacitor required at pin for stability. |
| 5 | 2IN+ | Channel 2 non-inverting input - electrically isolated from Channel 1 for dual-sensor signal conditioning. |
| 6 | 2IN− | Channel 2 inverting input - supports independent feedback networks per channel. |
| 7 | 2OUT | Channel 2 output - identical AC/DC performance to Pin 1; enables dual-path signal processing. |
| 8 | GND | Analog ground - must be tied to system AGND plane; separate from digital ground if mixed-signal layout. |
| 9 | NC | No internal connection - left unconnected; no routing or thermal relief required. |
| 10 | NC | No internal connection - unused pad; no electrical or thermal function. |
| 11 | NC | No internal connection - reserved for future variants; must remain floating. |
| 12 | 1SHDN | Channel 1 shutdown control - logic-high disables output and reduces IDD to <1.5 µA; compatible with 3.3 V GPIO. |
| 13 | NC | No internal connection - not bonded; no trace routing needed. |
| 14 | 2SHDN | Channel 2 shutdown control - independently controllable; enables asymmetric power gating in multi-stage filters. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 100 mV of VDD and GND at 2.2 mA load - eliminates level-shifting circuitry for 3.3 V ADC interfaces. |
| Low THD+N (0.005%) | Enables clean analog transmission in telecom line drivers and audio preamps without post-filtering. |
| Independent per-channel shutdown | Reduces total system quiescent current by >99% when one channel is idle - critical for duty-cycled sensor systems. |
| High CMMR (≥82 dB) | Maintains accuracy in noisy industrial environments where common-mode interference exceeds 1 Vpp. |
| Automotive qualification (AEC-Q100) | Validated for use in engine control units, body electronics, and ADAS sensor modules per Grade 2 requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2773IDR | Same architecture and specs, but in SOIC-8 package (not DIP); no shutdown pins; rated for −40°C to 125°C. | Lacks per-channel shutdown; unsuitable for power-gated designs; requires surface-mount assembly. | Select TLV2773IDR only if SOIC footprint and absence of shutdown control are acceptable. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift; 6 µV max VIO; higher 350 nA IB; 17 µA supply current per channel. | Better DC precision but higher power; no shutdown; limited to 5.5 V max supply; not AEC-Q100 qualified. | Choose OPA2333AIDR only when ultra-low drift dominates over power, temperature range, and automotive compliance. |
Compared with TLV2773IDR, TLV2773AIN offers through-hole DIP packaging and independent shutdown control - essential for serviceable automotive modules and dynamic power management. Against OPA2333AIDR, it trades zero-drift precision for lower quiescent current, wider temperature range, and AEC-Q100 qualification - making it the preferred choice for cost-sensitive, high-reliability automotive signal chains.

FAQ
What is the operating temperature range of the TLV2773AIN?
The TLV2773AIN is rated for operation from −40°C to +125°C and is qualified to AEC-Q100 Grade 2 standards. This makes it suitable for under-hood automotive applications and industrial environments where ambient temperatures exceed 85°C. Electrical specifications including input offset voltage, supply current, and THD+N are guaranteed across this full range.
Does the TLV2773AIN support rail-to-rail input as well as output?
No, the TLV2773AIN 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 3.7 V at VDD = 5 V), meaning it cannot accept signals at the positive rail. For true rail-to-rail input capability, consider TI's TLV246x or OPAx320 families - but those lack the TLV2773AIN's micropower shutdown and automotive qualification.
How does the shutdown functionality work on the TLV2773AIN?
The TLV2773AIN provides two dedicated shutdown pins: Pin 12 (1SHDN) for Channel 1 and Pin 14 (2SHDN) for Channel 2. Driving either pin high (≥2.0 V) disables its respective amplifier output and reduces that channel's supply current to <1.5 µA. Both channels remain active when shutdown pins are low or floating (internal pull-down not present - external pull-down recommended for default-on behavior).
What is the maximum load the TLV2773AIN can drive while maintaining rail-to-rail output swing?
The TLV2773AIN maintains rail-to-rail output swing into loads ≥600 Ω, as verified by THD+N = 0.005% at 1 kHz with 600 Ω termination. At 2.2 mA load (typical for 1 Vpp into 455 Ω), VOL = 0.21 V and VOH = 4.7 V at VDD = 5 V - confirming usable swing within 100 mV of both rails. For heavier loads, output swing compresses and THD increases.
Is the TLV2773AIN pin-compatible with other devices in the TLV277x family?
No - the TLV2773AIN (14-pin DIP) is not pin-compatible with TLV2772 (8-pin SOIC/DGK) or TLV2774 (14-pin SOIC). Its 14-pin DIP layout with dual shutdown pins and NC placeholders is unique within the family. Direct replacement requires PCB redesign. Always verify pinout against the "TLV277x PACKAGE PINOUTS" diagram in SLOS209G Rev F, Page 4.
