Product details
Overview
TLV2773CDR from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for single-supply portable and automotive 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 - enabling high-fidelity signal conditioning in ADC driver and telecom line-driver circuits.
For engineers reviewing the TLV2773CDR datasheet, TLV2773CDR pinout, TLV2773CDR application, or TLV2773CDR equivalent, this page provides verified electrical specifications, MSOP-10 package layout, shutdown functionality details, real-world use cases in precision sensing and low-voltage analog front-ends, and two validated alternative parts with documented functional trade-offs.
Technical Context
The TLV2773CDR integrates two independent high-speed CMOS op-amps with micropower shutdown control (IDD < 1 µA), rail-to-rail output swing, and low THD+N (0.005% into 600 Ω). Its architecture supports stable unity-gain operation with 46° phase margin and 12 dB gain margin at 5 V supply.
It is characterized across 0°C to 70°C (C-suffix), features 17 nV/√Hz input noise voltage at 10 kHz, 2 pA input bias current, and maintains 13 V/mV minimum large-signal differential gain under full load - making it suitable for precision DC-coupled amplification and AC-critical signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ - enables faithful reproduction of fast transients up to ~1.7 MHz full-power bandwidth into 10 kΩ. |
| Gain-Bandwidth Product | 5.1 MHz typ - supports stable closed-loop gain ≥ 2 at frequencies up to ~2.5 MHz. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤ 0.36 mV DC error in unity-gain buffer configurations. |
| Supply Current (per channel) | 1 mA typ at 5 V - allows dual-opamp operation within 2 mA total, ideal for battery-powered systems. |
| Rail-to-Rail Output | Swings within 0.1 V of rails at 2.2 mA load - maximizes dynamic range when interfacing with 3.3 V or 5 V ADCs. |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets audio-grade line-driver requirements without external compensation. |
| Shutdown Current | 0.8–1.5 µA per channel - reduces system standby power by >99.9% versus active mode. |
Pinout & Package
TLV2773CDR is packaged in a 10-pin MSOP (DGS) with exposed thermal pad. The package measures 3.0 mm × 3.0 mm × 1.0 mm and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives loads up to ±50 mA; rail-to-rail swing supports wide output headroom. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance node (10¹² Ω); sensitive to PCB leakage and guarding. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - matched to Pin 2 for optimal common-mode rejection. |
| 4 | GND | Analog ground reference - must be low-impedance and separated from digital ground to minimize noise coupling. |
| 5 | VDD | Positive supply rail - accepts 2.5 V to 5.5 V; bypass capacitor (0.1 µF) required near pin. |
| 6 | 2IN+ | Non-inverting input of Channel 2 - electrically isolated from Channel 1 inputs; shares same VDD/GND. |
| 7 | 2IN− | Inverting input of Channel 2 - symmetrical layout to Pin 2; supports differential input configurations. |
| 8 | 2OUT | Output of Channel 2 - independently controllable; identical AC/DC specs to Pin 1. |
| 9 | 2SHDN | Active-low shutdown enable for Channel 2 - pulls output to high-Z state when logic low. |
| 10 | 1SHDN | Active-low shutdown enable for Channel 1 - independent control allows selective channel disabling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale signal fidelity into 3.3 V or 5 V SAR ADC reference buffers without clipping. |
| Micropower shutdown mode | Reduces per-channel current to sub-µA level - critical for always-on sensor nodes with duty-cycled amplification. |
| Low THD+N (0.005%) | Enables clean analog transmission in telecom line drivers and audio preamps without post-filtering. |
| High slew rate + GBW synergy | 10.5 V/µs / 5.1 MHz combination supports wideband pulse amplification (e.g., ultrasound receive chains). |
| Extended temperature support | Specified over 0°C to 70°C (C-suffix) - validated for industrial control and automotive cabin electronics. |
| Low input bias current (2 pA) | Minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, photodiode TIA feedback). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462CDR | Lower slew rate (1.6 V/µs), higher supply current (550 µA/channel), rail-to-rail input/output. | Better DC precision (250 µV VIO), but insufficient speed for >100 kHz signal conditioning. | Select when ultra-low offset and input/output swing are prioritized over bandwidth and power. |
| OPA2340UA | Higher slew rate (20 V/µs), higher supply current (800 µA/channel), rail-to-rail output only. | Superior settling time (0.4 µs to 0.01%), but lacks independent shutdown pins and has higher cost. | Select when driving multiplexed ADCs requiring fast settling and minimal glitch energy. |
Compared with TLV2773CDR, TLV2462CDR trades bandwidth and power efficiency for improved DC accuracy, while OPA2340UA delivers faster transient response at the expense of shutdown flexibility and quiescent current - making TLV2773CDR optimal for battery-constrained, multi-channel, moderate-bandwidth systems requiring independent channel control.

FAQ
What is the maximum supply voltage for TLV2773CDR?
The absolute maximum supply voltage for TLV2773CDR is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation at 5.5 V ensures full rail-to-rail output swing and specified AC performance; exceeding 5.5 V risks parametric degradation and reduced reliability. TI characterizes all key parameters at both 2.7 V and 5 V supplies.
Does TLV2773CDR support true rail-to-rail input?
No, TLV2773CDR 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 5 V supply), meaning it cannot accept signals at the positive rail. This limitation must be considered in level-shifting or high-side sensing designs where input signals approach VDD.
How does the shutdown function operate on TLV2773CDR?
TLV2773CDR provides independent active-low shutdown control: Pin 10 (1SHDN) disables Channel 1, and Pin 9 (2SHDN) disables Channel 2. When pulled low, each channel's output enters high-impedance state and supply current drops to ≤1.5 µA per channel. Both pins must be held high (≥2.0 V) for normal operation.
What is the thermal performance of TLV2773CDR in MSOP-10 (DGS) package?
In the MSOP-10 (DGS) package, TLV2773CDR has a thermal resistance θJA of 150°C/W and a power dissipation rating of 424 mW at TA ≤ 25°C, derating at 3.4 mW/°C above 25°C. At 70°C ambient and 2 mA total supply current (5 V), junction temperature remains within safe limits (<105°C) with standard PCB copper area.
Is TLV2773CDR qualified for automotive applications?
TLV2773CDR (C-suffix) is rated for 0°C to 70°C and is not AEC-Q200 qualified. For automotive use, TI offers the TLV2773IDR (I-suffix, −40°C to 125°C) and TLV2773AIDR (A-suffix, −40°C to 125°C with tighter 1.6 mV VIO max), both qualified to automotive standards and available in the same DGS package.
