Product details
Overview
TLV2773CDGS from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier with 5.1 MHz gain-bandwidth product, 10.5 V/µs slew rate, and 1 mA per-channel supply current at 5 V. It operates from 2.5 V to 5.5 V single supply and features micropower shutdown (<1 µA), making it suitable for portable instrumentation front-ends and low-power sensor signal conditioning.
For engineers reviewing the TLV2773CDGS datasheet, TLV2773CDGS pinout, TLV2773CDGS application, or TLV2773CDGS equivalent, key selection criteria include its 360 µV input offset voltage, 17 nV/√Hz input noise, −55°C to 125°C military-grade temperature rating (M-suffix family), and MSOP-10 package with integrated shutdown control per channel.
Technical Context
The TLV2773CDGS implements a high-speed CMOS input stage with rail-to-rail output swing and internal shutdown logic enabling independent channel enable/disable. Its 5.1 MHz bandwidth and 10.5 V/µs slew rate support fast-settling analog-to-digital converter (ADC) driving applications while maintaining 0.005% THD+N into 600 Ω.
It delivers 2 pA input bias current and 360 µV input offset voltage across −55°C to 125°C, supporting precision measurement in harsh environments. The device is characterized at both 2.7 V and 5 V, with specified performance over full industrial and extended military temperature ranges.

Pinout & Package
TLV2773CDGS is housed 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 supports fine-pitch surface-mount assembly and provides enhanced thermal dissipation versus SOIC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - Rail-to-rail swing (0.1 V to VDD − 0.2 V) capable of sourcing/sinking ±2.2 mA. |
| 2 | 1IN− | Inverting input of Channel 1 - High-impedance CMOS node (10¹² Ω) with 2 pA bias current. |
| 3 | 1IN+ | Noninverting input of Channel 1 - Matches 1IN− in offset and noise; used for precision differential or single-ended gain stages. |
| 4 | GND | Analog ground reference - Must be low-impedance connection; separates signal return from power return in mixed-signal layouts. |
| 5 | VDD | Positive supply rail - Accepts 2.5 V to 5.5 V; bypass capacitor (0.1 µF) required at pin for stability. |
| 6 | 2OUT | Output of Channel 2 - Electrically identical to 1OUT; enables dual-path signal processing or composite amplification. |
| 7 | 2IN− | Inverting input of Channel 2 - Independent of Channel 1; supports fully differential or isolated dual-channel topologies. |
| 8 | 2IN+ | Noninverting input of Channel 2 - Used for matched gain configuration or independent sensor channel amplification. |
| 9 | 2SHDN | Channel 2 shutdown control - Active-low; pulls channel output to high-impedance state when logic low (<0.8 V). |
| 10 | 1SHDN | Channel 1 shutdown control - Active-low; enables independent power gating per amplifier for dynamic power management. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2772CDGK | Same family, 8-pin MSOP, no shutdown pins - lacks per-channel enable functionality. | Used where space-constrained dual op-amp is needed without dynamic power control. | Select TLV2772CDGK only if shutdown capability is unnecessary and board layout favors smaller 8-pin footprint. |
| OPA2340UA | Single-supply, rail-to-rail I/O, 5.5 MHz GBW, but higher 1.6 mA/channel supply current and no shutdown mode. | Preferred in high-fidelity audio paths where ultra-low distortion (0.0006% THD+N) outweighs power savings. | Choose OPA2340UA when THD+N < 0.001% is mandatory and system power budget allows +0.6 mA/channel overhead. |
Compared with TLV2772CDGK, TLV2773CDGS adds independent shutdown control per channel at the cost of two extra pins; compared with OPA2340UA, it trades 0.0044% higher THD+N for 37.5% lower active current and integrated power gating-critical for energy-constrained embedded systems.

FAQ
What is the maximum operating supply voltage for TLV2773CDGS?
The absolute maximum supply voltage for TLV2773CDGS 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 below 2.5 V may cause degraded AC performance including reduced slew rate and bandwidth. TI specifies full parametric performance only within the 2.5–5.5 V window, with characterization at both 2.7 V and 5 V nominal points. TLV2773CDGS must never be operated outside these limits in production designs.
Does TLV2773CDGS support true rail-to-rail input operation?
No, TLV2773CDGS 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 VDD = 5 V), meaning it cannot accept signals within 1.3 V of the positive rail. This limitation requires careful input biasing in single-supply configurations-for example, using a mid-rail reference or AC-coupled inputs when handling full-scale signals near VDD. Input stage architecture is CMOS-based, contributing to the 2 pA bias current and high input impedance.
How does the shutdown feature of TLV2773CDGS behave during power-up?
TLV2773CDGS has no built-in power-on reset for shutdown pins; both 1SHDN and 2SHDN default to high-impedance (inactive) at power-up, enabling both channels automatically. To ensure defined startup behavior, external pull-up resistors (typically 10–100 kΩ to VDD) are recommended on each SHDN pin. Without them, floating shutdown lines may cause erratic channel activation or increased start-up time due to capacitive coupling. TI confirms that the amplifier outputs enter high-impedance state only when SHDN is actively driven low (<0.8 V), not during undervoltage lockout.
Can TLV2773CDGS drive a 10-kΩ load with rail-to-rail output swing?
Yes, TLV2773CDGS maintains rail-to-rail output swing (within 0.1 V of GND and 0.2 V of VDD) when driving a 10-kΩ load at room temperature. Its output stage is specified for ±2.2 mA drive into 600 Ω, so loading with 10 kΩ imposes only 0.5 mA max current-well within capability. However, output voltage compliance degrades slightly at temperature extremes: at −55°C, high-level output drops to VDD − 0.3 V, and at 125°C, low-level rises to 0.25 V. For guaranteed rail-to-rail performance across full temperature range, keep load ≥10 kΩ and avoid heavy capacitive loads (>100 pF) without isolation resistance.
Is TLV2773CDGS qualified for automotive applications?
TLV2773CDGS itself carries the 'C' temperature suffix (0°C to 70°C) and is not AEC-Q200 qualified. However, the TLV2773 family includes automotive-grade variants: TLV2773IDGS (−40°C to 125°C, Q-temp) and TLV2773AIDGS (−40°C to 125°C, AEC-Q100 stress-tested). These share identical pinout, electrical specs, and MSOP-10 packaging but undergo additional automotive qualification testing. TLV2773CDGS is suitable for non-safety-critical consumer or industrial applications only; use TLV2773IDGS or TLV2773AIDGS for dashboard, ADAS, or powertrain subsystems.
