Product details
Overview
TLV2773IDGSR from Texas Instruments is a dual-channel, rail-to-rail output CMOS 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, and 360 µV input offset voltage at 5 V supply, operating from 2.5 V to 5.5 V. Its micropower shutdown mode (<1 µA per channel) and −40°C to 125°C temperature range make it suitable for automotive sensor front-ends and portable medical instrumentation.
For engineers reviewing the TLV2773IDGSR datasheet, TLV2773IDGSR pinout, TLV2773IDGSR application, or TLV2773IDGSR equivalent, key selection criteria include rail-to-rail output swing into 600-Ω loads, 0.005% THD+N at 1 kHz, 17 nV/√Hz input noise, and verified MSOP-10 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2773IDGSR employs a CMOS input stage with 2 pA input bias current and high-impedance differential input (10¹² Ω), enabling precision DC-coupled amplification in high-source-impedance sensor interfaces. Its unity-gain-stable architecture supports closed-loop gains ≥1 with 46° phase margin driving 600-Ω loads and 100-pF capacitive loads.
Each channel integrates independent shutdown control (1SHDN/2SHDN), allowing dynamic power management in multi-stage analog signal chains. The device is characterized across extended temperature ranges and specified for single-supply operation only - no dual-supply configuration support is provided.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical - enables faithful reproduction of fast transients in ADC driver and active filter applications |
| Gain-Bandwidth Product | 5.1 MHz typical - supports stable unity-gain buffers and 2nd-order filters up to ~800 kHz |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.07% error in 0.5 V full-scale industrial current-sense amplifiers |
| Supply Current (per channel) | 1 mA typical at 5 V - allows dual-channel operation within 2 mA total budget for battery-powered systems |
| Shutdown Current | <1 µA per channel - reduces system standby power by >99.9% when channels are inactive |
| Input Noise Voltage | 17 nV/√Hz at 10 kHz - preserves SNR in audio preamps and low-level sensor signal chains |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom line-driver spectral purity requirements |
Pinout & Package
TLV2773IDGSR is housed in a 10-pin MSOP (DGS) package with 0.5-mm pitch, 3.0 mm × 3.0 mm footprint, and exposed thermal pad (not electrically connected). Pin 1 is marked by a beveled edge or molded dot.
| 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 for Channel 1 - high common-mode rejection (82 dB min) rejects supply noise |
| 3 | 1IN+ | Non-inverting input for Channel 1 - 2 pA bias current minimizes error in high-Z pH or thermocouple sensors |
| 4 | GND | Analog ground reference - must be star-connected to minimize crosstalk between channels |
| 5 | VDD | Positive supply - accepts 2.5 V to 5.5 V; no reverse polarity protection |
| 6 | 2IN+ | Non-inverting input for Channel 2 - independent of Channel 1; no internal cross-coupling |
| 7 | 2IN− | Inverting input for Channel 2 - matched input capacitance (8 pF) ensures balanced AC response |
| 8 | 2OUT | Channel 2 output - capable of sourcing/sinking ±2.2 mA into 600-Ω load |
| 9 | 2SHDN | Active-low shutdown enable for Channel 2 - pulls to GND to disable; open-circuit defaults to active |
| 10 | 1SHDN | Active-low shutdown enable for Channel 1 - logic-compatible with 1.8-V microcontrollers |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 100 mV of VDD and GND at 2.2 mA load - eliminates level-shifting circuitry for 3.3-V ADCs |
| Micropower shutdown | Reduces per-channel IDD to <1 µA - enables duty-cycled operation in energy-harvesting sensor nodes |
| Low distortion at 600 Ω | 0.005% THD+N at 1 kHz - satisfies ITU-T G.712 telecom line-driver linearity specs |
| Extended temperature range | Specified from −40°C to +125°C - qualified for under-hood automotive and industrial control environments |
| High output drive | ±2.2 mA into 600 Ω - drives multiple ADC inputs or coaxial cables without external buffers |

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 electrical specs; SOIC-8 package (larger footprint, no shutdown pins) | Lacks independent channel shutdown; unsuitable for dynamic power-gating architectures | Select TLV2773IDR only if board space permits SOIC-8 and shutdown control is unnecessary |
| OPA2333AIDRGT | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2773IDGSR's 2 µV/°C; higher 350 nA supply current | Better DC stability over temperature; higher power consumption limits use in ultra-low-power designs | Choose OPA2333AIDRGT when long-term offset drift dominates error budget, not raw power |
Compared with TLV2773IDR, TLV2773IDGSR offers independent shutdown control in a 3×3 mm MSOP-10, while OPA2333AIDRGT trades 350× higher quiescent current for sub-μV offset drift - making TLV2773IDGSR optimal for cost-sensitive, space-constrained, and dynamically powered systems requiring <1 µA shutdown.

FAQ
What is the maximum supply voltage rating for TLV2773IDGSR?
The absolute maximum supply voltage for TLV2773IDGSR is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks permanent damage and violates the device's specified performance envelope. At 5 V, TLV2773IDGSR achieves its full 10.5 V/µs slew rate and 5.1 MHz bandwidth, while maintaining 1 mA per channel supply current.
Does TLV2773IDGSR support dual-supply operation?
No, TLV2773IDGSR is specified for single-supply operation only. Its input common-mode range extends from GND to VDD − 1.3 V, and its rail-to-rail output swings within 100 mV of both rails. Attempting dual-supply use (e.g., ±2.5 V) violates the absolute maximum ratings and may cause latch-up or parametric failure. For dual-supply applications, TI recommends the TLV2772 series.
How does the shutdown function operate on TLV2773IDGSR?
TLV2773IDGSR features two independent active-low shutdown pins: 1SHDN (Pin 10) controls Channel 1, and 2SHDN (Pin 9) controls Channel 2. Pulling either pin to GND disables its respective amplifier, reducing supply current to <1 µA per channel. Leaving the pin open or tied to VDD keeps the channel active. No external pull-up is required - internal weak pull-ups ensure default active state.
What is the thermal performance of TLV2773IDGSR in MSOP-10 package?
In the MSOP-10 (DGS) package, TLV2773IDGSR has a thermal resistance θJA of 120°C/W and a derating factor of 3.4 mW/°C above TA = 25°C. At 125°C ambient and 5 V supply, its maximum continuous power dissipation is 85 mW. The exposed thermal pad improves heat transfer but is not electrically connected - it must be soldered to a thermal copper pour for optimal performance.
Is TLV2773IDGSR qualified for automotive applications?
Yes, TLV2773IDGSR carries the "I" temperature suffix (−40°C to +125°C) and is explicitly listed in TI's Q-Temp Automotive qualification program. It meets AEC-Q100 stress test requirements for automotive-grade reliability and is approved for use in non-safety-critical automotive subsystems including cabin climate control, body electronics, and infotainment sensor interfaces.
