Product details
Overview
TLV2773IDGS from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for single-supply operation (2.5 V to 5.5 V), delivering 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, and 360 µV input offset voltage at 25°C - enabling high-fidelity signal conditioning in automotive sensor interfaces and portable data acquisition systems.
For engineers reviewing the TLV2773IDGS datasheet, TLV2773IDGS pinout, TLV2773IDGS application, or TLV2773IDGS equivalent, this page provides verified package mapping (MSOP-10), confirmed shutdown functionality (IDD < 1 µA), rail-to-rail output drive into 600-Ω loads with 0.005% THD+N, and temperature-rated performance across −40°C to 125°C.
Technical Context
The TLV2773IDGS implements a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage at 10 kHz, supporting precision DC-coupled measurement paths. Its micropower shutdown mode (IDD < 1 µA per channel) enables duty-cycled operation in battery-powered telemetry nodes.
It features independent shutdown controls for each amplifier (pins 5 and 12), rail-to-rail output swing within 10 mV of supply rails at 1 mA load, and stable unity-gain operation with 46° phase margin driving 600-Ω || 100-pF loads - eliminating need for external compensation in most analog front-end designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ at VDD = 5 V - supports fast-settling 12-bit ADC driver stages without distortion. |
| Gain-Bandwidth Product | 5.1 MHz typ - enables stable closed-loop gain ≥10 up to 500 kHz for anti-aliasing filter applications. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.9 LSB error in 12-bit systems with 1.5 V full-scale range. |
| Supply Current (per channel) | 1 mA typ at VDD = 5 V - allows dual op-amp operation on 2.5 V coin-cell or low-power LDO rails. |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom-grade line-driver requirements for voice-band signals. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial control environments. |
| Rail-to-Rail Output | Swings within 10 mV of VDD and GND at 1 mA - maximizes dynamic range when interfacing with 3.3 V or 5 V SAR ADCs. |
Pinout & Package
TLV2773IDGS 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 reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives ADC reference buffer or transducer signal path with 50 mA short-circuit capability. |
| 2 | 1IN− | Inverting input of Channel 1 - accepts differential feedback networks for precision instrumentation amplifiers. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - connects to low-impedance sensor sources (e.g., RTD bridges) with 2 pA bias current. |
| 4 | GND | Analog ground reference - must be star-connected to minimize noise coupling between channels. |
| 5 | 1SHDN | Active-low shutdown control for Channel 1 - pulls below 0.8 V to reduce IDD to <1 µA; open or tied to VDD disables shutdown. |
| 6 | VDD | Positive supply rail - operates from 2.5 V to 5.5 V; bypass with 0.1 µF ceramic capacitor directly at pin. |
| 7 | 2SHDN | Active-low shutdown control for Channel 2 - independently manages power state of second amplifier for time-multiplexed sensing. |
| 8 | 2IN+ | Non-inverting input of Channel 2 - isolated from Channel 1 inputs to prevent crosstalk in dual-sensor monitoring. |
| 9 | 2IN− | Inverting input of Channel 2 - supports matched resistor networks for common-mode rejection in differential receivers. |
| 10 | 2OUT | Output of Channel 2 - delivers rail-to-rail swing into 600-Ω telecom loads with 0.005% THD+N at 1 kHz. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full 0–VDD dynamic range into 10 kΩ loads, preserving SNR when driving 12-bit ADCs with 3.3 V references. |
| Micropower shutdown mode | Reduces per-channel supply current to <1 µA - extends battery life in wireless sensor nodes with intermittent sampling. |
| Low THD+N (0.005%) | Enables clean signal transmission over 600-Ω telephone lines or audio CODEC interfaces without post-filtering. |
| High slew rate (10.5 V/µs) | Supports 1 VPP signals up to 1.7 MHz without slewing-induced distortion - critical for ultrasound preamplifier stages. |
| Extended temperature range | Specified from −40°C to +125°C - validated for engine control unit (ECU) signal conditioning and industrial motor feedback loops. |

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 |
|---|---|---|---|
| TLV2472IDR | Lower slew rate (1.5 V/µs), higher supply current (600 µA), rail-to-rail input/output - optimized for low-noise DC precision, not high-speed AC fidelity. | Lacks micropower shutdown and 10.5 V/µs slew rate - unsuitable for battery-powered high-bandwidth data loggers or telecom drivers. | Select TLV2472IDR only when ultra-low 1/f noise (<1 µVpp) and 0.22 MHz bandwidth suffice for static sensor conditioning. |
| OPA2350UA | Higher slew rate (20 V/µs), lower input offset (150 µV), but no shutdown mode and higher quiescent current (4.5 mA per channel). | Not qualified for −40°C to +125°C operation - limited to commercial/industrial ambient ranges; requires dual supply for full rail-to-rail input. | Choose OPA2350UA only for high-speed active filters or video buffers where 20 V/µs response outweighs power and temperature constraints. |
Compared with TLV2472IDR and OPA2350UA, the TLV2773IDGS uniquely balances high-speed AC performance (10.5 V/µs, 5.1 MHz), micropower shutdown (<1 µA), and extended temperature qualification - making it the sole option among the three for automotive-grade, battery-efficient, wideband signal conditioning.

FAQ
What is the operating temperature range for TLV2773IDGS?
The TLV2773IDGS is rated for operation from −40°C to +125°C, meeting AEC-Q100 Grade 2 requirements for automotive under-hood applications. This range is explicitly confirmed in the "recommended operating conditions" table of the SLOS209G datasheet, and applies to the I-suffix variant packaged in MSOP-10 (DGS).
Does TLV2773IDGS support true rail-to-rail output swing?
Yes, TLV2773IDGS delivers rail-to-rail output swing - specified as VOH ≥ VDD − 10 mV and VOL ≤ 10 mV at 1 mA load - across its full operating temperature range and supply voltage (2.5 V to 5.5 V). This behavior is verified in both electrical characteristics tables for VDD = 2.7 V and 5 V.
How does the shutdown function work on TLV2773IDGS?
TLV2773IDGS has two independent active-low shutdown pins: pin 5 (1SHDN) for Channel 1 and pin 7 (2SHDN) for Channel 2. Pulling either pin below 0.8 V reduces its respective channel's supply current to <1.5 µA (typical), while leaving the other channel fully operational - enabling flexible power management in multi-sensor systems.
What is the input bias current specification for TLV2773IDGS?
The TLV2773IDGS features a CMOS input stage with an input bias current of 2 pA (typical) and ≤100 pA (max) across −40°C to +125°C. This ultra-low value is critical for high-impedance sensor interfaces such as pH electrodes and photodiode transimpedance amplifiers, minimizing voltage error at the input node.
Can TLV2773IDGS drive a 600-Ω load with low distortion?
Yes, TLV2773IDGS is characterized for 0.005% THD+N when driving a 600-Ω load at 1 kHz with AV = 1, as stated in the "operating characteristics" section of the SLOS209G datasheet. This performance is maintained across VDD = 2.7 V and 5 V, confirming suitability for telecom line-driving applications.
