Product details
Overview
TLV2773IDR 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, and 1 mA per-channel supply current across 2.5 V to 5.5 V operation - enabling high-fidelity sensor front-ends and ADC driver stages in automotive and industrial control modules.
For engineers reviewing the TLV2773IDR datasheet, TLV2773IDR pinout, TLV2773IDR application, or TLV2773IDR equivalent, key selection criteria include its micropower shutdown mode (IDD < 1 µA), −40°C to 125°C temperature rating, low THD+N (0.005% into 600 Ω), and MSOP-10 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2773IDR 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 contribution. Its rail-to-rail output swing enables full dynamic range utilization when driving SAR or sigma-delta ADC reference inputs at low supply voltages.
It integrates independent shutdown controls per channel (1SHDN and 2SHDN), allowing dynamic power management in multi-stage analog chains. The device is characterized for stable operation with capacitive loads up to 100 pF and maintains ≥46° phase margin into 600-Ω loads, ensuring robustness in telecom line-driver and active filter configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ - supports fast transient response in active filters and buffer stages driving ADC sample-and-hold circuits. |
| Gain-Bandwidth Product | 5.1 MHz typ - enables stable unity-gain and moderate-gain configurations up to ~100 kHz with minimal phase lag. |
| Input Offset Voltage | 360 µV max - ensures ≤0.014% gain error in 2.5 V full-scale instrumentation amplifiers. |
| Supply Current per Channel | 1 mA typ at 5 V - allows dual op-amp operation within 2 mA total budget for battery-powered data loggers. |
| Rail-to-Rail Output | Swings within 100 mV of VDD and GND - maximizes signal headroom when interfacing with 3.3 V or lower ADC references. |
| Shutdown Current | <1 µA per channel - reduces system standby power by >99.9% versus active mode, critical for always-on sensor nodes. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial motor-control environments without derating. |
Pinout & Package
TLV2773IDR is housed in a 10-pin MSOP (DGS) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm. This thermally enhanced, surface-mount package supports high-density routing and improved power dissipation over standard SOIC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Channel 1 output - drives external load or next-stage input with rail-to-rail swing capability. |
| 2 | 1IN− | Inverting input for Channel 1 - accepts feedback network or differential signal path. |
| 3 | 1IN+ | Non-inverting input for Channel 1 - connects to sensor, reference, or signal source with high-impedance interface. |
| 4 | GND | Analog ground reference - must be tied to low-impedance system ground plane to minimize noise coupling. |
| 5 | VDD | Positive supply rail - accepts 2.5 V to 5.5 V single supply; decoupling capacitor required at pin. |
| 6 | 2IN+ | Non-inverting input for Channel 2 - electrically isolated from Channel 1; supports dual-sensor conditioning. |
| 7 | 2IN− | Inverting input for Channel 2 - used for differential gain configuration or unity-gain buffer feedback. |
| 8 | 2OUT | Channel 2 output - independently routable; shares same rail-to-rail drive strength as Channel 1. |
| 9 | 2SHDN | Active-low shutdown enable for Channel 2 - pulls low to disable output and reduce IDD to <1 µA. |
| 10 | 1SHDN | Active-low shutdown enable for Channel 1 - independent control allows asymmetric power gating in multi-stage designs. |

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 |
|---|---|---|---|
| TLV2772IDR | Same family, dual-channel, but lacks per-channel shutdown pins; uses 8-pin SOIC or MSOP packages without SHDN terminals. | No independent channel disable capability - unsuitable for asymmetric power-gated architectures requiring selective channel sleep. | Select TLV2772IDR only if board layout constraints preclude 10-pin MSOP or shutdown functionality is unnecessary. |
| OPA2350UA | Higher slew rate (38 V/µs), lower noise (7 nV/√Hz), but higher supply current (4.9 mA/ch); no shutdown mode; rated only to 85°C. | Better dynamic performance for high-speed data acquisition, but incompatible with automotive or extended-temperature industrial use cases. | Choose OPA2350UA only for lab-grade instrumentation where speed and noise dominate over temperature range and power efficiency. |
Compared with TLV2772IDR, TLV2773IDR adds independent shutdown control and fits in compact MSOP-10 - critical for automotive ECUs with strict power sequencing. Versus OPA2350UA, it trades raw speed for guaranteed −40°C to 125°C operation and 75% lower quiescent current, making it optimal for embedded edge sensing.

FAQ
What is the maximum operating supply voltage for TLV2773IDR?
The absolute maximum supply voltage for TLV2773IDR 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 TI's specified conditions; designs should maintain VDD ≤ 5.5 V with appropriate decoupling to ensure long-term reliability and parametric compliance per SLOS209G.
Does TLV2773IDR support true rail-to-rail input operation?
No, TLV2773IDR 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. For full rail-to-rail input capability, consider TI's TLV246x or OPAx320 families - TLV2773IDR is optimized for output headroom-critical applications like ADC drivers.
How does the shutdown function behave on TLV2773IDR?
TLV2773IDR provides two independent active-low shutdown pins: 1SHDN (Pin 10) and 2SHDN (Pin 9). Pulling either pin low disables its respective amplifier output, reducing that channel's supply current to <1 µA. Both channels remain fully functional when both pins are high (≥2 V). No external pull-up is required - internal weak pull-ups hold pins high during power-up reset sequences.
Can TLV2773IDR drive a 100-pF capacitive load stably?
Yes, TLV2773IDR is characterized for stable operation with 100-pF capacitive loads and 600-Ω series resistance, maintaining ≥46° phase margin and 12 dB gain margin per SLOS209G. This makes it suitable for driving ADC input capacitance, coaxial cables, or multi-stage filter nodes without external isolation resistors - unlike many general-purpose op-amps requiring added series resistance for stability.
What is the typical input offset voltage drift over temperature for TLV2773IDR?
The TLV2773IDR has a temperature coefficient of input offset voltage (αVIO) of 2 µV/°C maximum across −40°C to +125°C. At 25°C, typical VIO is 360 µV; over the full range, worst-case drift contributes ≤350 µV additional error (175°C × 2 µV/°C), keeping total offset within 710 µV - sufficient for 12-bit accuracy in 2.5 V full-scale systems.
