Product details
Overview
TLV2773CD from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for precision analog signal conditioning in single-supply systems. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 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 sensor front-ends and ADC driver stages in portable industrial instrumentation.
For engineers reviewing the TLV2773CD datasheet, TLV2773CD pinout, TLV2773CD application, or TLV2773CD equivalent, key selection criteria include its micropower shutdown mode (<1 µA per channel), low THD+N (0.005% at 1 kHz driving 600 Ω), and guaranteed operation across 0°C to 70°C with MSOP-10 packaging.
Technical Context
The TLV2773CD employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, supporting high-impedance source interfacing without significant error. Its rail-to-rail output stage delivers full-swing capability into loads down to 600 Ω while maintaining <0.01% distortion - critical for driving SAR and sigma-delta ADC reference inputs.
It integrates independent shutdown control for each amplifier (pins 5 and 12), enabling dynamic power management in multi-stage signal chains. The device is characterized at both 2.7 V and 5 V supply voltages, with stable phase margin (46°) and gain margin (12 dB) under 600 Ω load and 100 pF capacitive loading - ensuring robust closed-loop stability in real-world PCB layouts.

| Gain-Bandwidth Product | 5.1 MHz typ - supports stable unity-gain buffer configurations and closed-loop gains up to ~100 at 50 kHz. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.014% full-scale error in 2.5 V-range 12-bit ADC interfaces. |
| Supply Current per Channel | 1 mA typ at 2.7 V - allows dual-opamp operation within 2.1 mW total power budget at 2.7 V. |
| Shutdown Current | <1 µA per channel - reduces system standby power by >99.9% when amplifiers are inactive. |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom-grade line driver requirements and high-fidelity audio preamp specs. |

Pinout & Package
TLV2773CD is packaged in a 10-pin MSOP (DGS) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm. Pin 1 is marked by a beveled edge or molded dot; the package is RoHS-compliant and moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - rail-to-rail capable, drives 600 Ω load with <0.01% THD+N. |
| 2 | 1IN− | Inverting input of Channel 1 - CMOS input with 2 pA bias current, supports high-Z sensor interfaces. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - matched to Pin 2 for optimal common-mode rejection (CMRR ≥82 dB). |
| 4 | GND | Analog ground reference - must be connected to low-impedance system ground plane for noise immunity. |
| 5 | 1SHDN | Active-low shutdown control for Channel 1 - pulls to GND to disable amplifier; open or high = active. |
| 6 | VDD | Positive supply rail - accepts 2.5 V to 5.5 V; bypass with 0.1 µF ceramic capacitor near pin. |
| 7 | 2IN+ | Non-inverting input of Channel 2 - electrically identical to Pin 3; supports differential pair configuration. |
| 8 | 2IN− | Inverting input of Channel 2 - matched to Pin 7; enables precision instrumentation amplifier topologies. |
| 9 | 2OUT | Output of Channel 2 - independently buffered; no crosstalk with Channel 1 (PSRR ≥84 dB). |
| 10 | 2SHDN | Active-low shutdown control for Channel 2 - fully independent of Pin 5 for asymmetric power management. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers 0.1 V to VDD − 0.1 V output range at 2.2 mA load - eliminates headroom loss when driving ADC references. |
| Low input noise voltage | 17 nV/√Hz at 10 kHz - preserves SNR in low-level thermocouple or strain gauge amplification stages. |
| Independent dual shutdown | Two dedicated SHDN pins allow selective channel disabling - essential for adaptive power scaling in battery-powered data acquisition. |
| High CMRR and PSRR | ≥82 dB CMRR and ≥84 dB PSRR - rejects supply ripple and common-mode interference in noisy industrial environments. |
| Specified for 2.7 V and 5 V operation | Full parametric validation at both voltages - simplifies design reuse across 3.3 V and 5 V legacy systems without derating. |

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 |
|---|---|---|---|
| TLV2462CD | Lower slew rate (1.6 V/µs), higher supply current (550 µA/channel), I/O rail-to-rail, wider VDD range (2.7–6 V) | Better DC precision (150 µV VIO), but insufficient bandwidth/slew for fast ADC drivers or telecom line stages | Select TLV2462CD only when ultra-low offset dominates over speed and power constraints |
| OPA2340UA | Higher slew rate (6 V/µs), lower noise (12 nV/√Hz), no shutdown, SO-8 package | Superior AC performance and noise floor, but lacks micropower shutdown and MSOP-10 footprint | Choose OPA2340UA for high-fidelity audio or medical sensing where shutdown is unnecessary and board space permits SO-8 |
Compared with TLV2773CD, TLV2462CD trades speed and power efficiency for better DC accuracy, while OPA2340UA offers superior noise and slew performance but sacrifices shutdown capability and compact packaging - making TLV2773CD uniquely balanced for portable, power-aware precision signal chains.

FAQ
What is the maximum operating supply voltage for TLV2773CD?
The absolute maximum supply voltage for TLV2773CD is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks permanent damage, while operation below 2.5 V may cause degraded slew rate, bandwidth, and output swing. All electrical specifications in the datasheet are validated within the 2.5–5.5 V range, with full characterization at 2.7 V and 5 V.
Does TLV2773CD support true rail-to-rail input operation?
No, TLV2773CD features rail-to-rail *output* swing 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 is explicitly defined in the "Recommended Operating Conditions" table and confirmed across all temperature ranges for the CD grade. Input signals must remain ≥1.3 V below VDD to maintain specified CMRR and offset performance.
How does the shutdown function behave on TLV2773CD?
TLV2773CD provides two independent active-low shutdown pins: Pin 5 (1SHDN) for Channel 1 and Pin 10 (2SHDN) for Channel 2. Pulling either pin to GND disables its respective amplifier, reducing supply current to <1.5 µA per channel. Leaving the pin open or pulled high (≥2 V) enables normal operation. Shutdown state does not affect other channels, and output pins enter high-impedance state during shutdown - preventing loading of downstream circuitry.
Can TLV2773CD drive a 50 Ω load reliably?
No, TLV2773CD is not rated for continuous 50 Ω loads. Its output stage is specified for 600 Ω minimum load (per THD+N and settling time tests), with short-circuit current limited to ±50 mA. Driving 50 Ω would exceed safe operating area limits, causing excessive power dissipation (>100 mW per channel at 2.5 V swing), thermal stress, and potential output stage failure. For 50 Ω interfaces, use purpose-built line drivers such as THS3091 or LMH6702 instead of TLV2773CD.
Is TLV2773CD pin-compatible with other devices in the TLV277x family?
No, TLV2773CD is not pin-compatible with other TLV277x variants. While TLV2772 uses an 8-pin SOIC or MSOP package, TLV2773CD uses a 10-pin MSOP (DGS) package with dedicated shutdown pins for each channel. TLV2774/TLV2775 use 14- and 16-pin packages respectively. The 10-pin DGS layout is unique to TLV2773 and TLV2775 - confirming that TLV2773CD requires its own PCB footprint and cannot be substituted without layout revision.
