Product details
Overview
TLV2773CDGSR from Texas Instruments is a dual CMOS operational amplifier with rail-to-rail output, 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 is specified for 0°C to 70°C ambient, making it suitable for precision analog front-ends in portable instrumentation and sensor signal conditioning.
For engineers reviewing the TLV2773CDGSR datasheet, TLV2773CDGSR pinout, TLV2773CDGSR application, or TLV2773CDGSR equivalent, key selection criteria include its micropower shutdown mode (IDD < 1 µA), low 360 µV input offset voltage, 17 nV/√Hz input noise, 2 pA input bias current, and MSOP-10 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2773CDGSR integrates two independent high-speed CMOS op-amps sharing a common 2.5–5.5 V supply and ground. Each channel features unity-gain-stable compensation, rail-to-rail output swing, and micropower shutdown control via dedicated SHDN pins (pins 5 and 12).
It delivers 5.1 MHz bandwidth and 10.5 V/µs slew rate while maintaining low distortion (0.005% THD+N into 600 Ω) and stable phase margin (46°) under 600 Ω load with 100 pF capacitive load - enabling direct driving of ADC reference inputs and telecom line drivers without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports single-supply operation in battery-powered systems down to 2.5 V cutoff. |
| Gain-Bandwidth Product | 5.1 MHz - enables stable closed-loop gain up to ~10× at 500 kHz for anti-aliasing filter stages. |
| Slew Rate | 10.5 V/µs - ensures faithful reproduction of fast 1-Vpp signals up to ~1.7 MHz without slewing distortion. |
| Input Offset Voltage | 360 µV max - minimizes DC error in precision transducer amplification and 12-bit+ data acquisition paths. |
| Supply Current per Channel | 1 mA at 5 V - allows dual-channel operation within 2 mA total, critical for always-on sensor nodes. |
| Shutdown Current | < 1 µA per channel - reduces system standby power by >1000× versus active mode. |
| Input Noise Voltage | 17 nV/√Hz at 10 kHz - preserves SNR in low-level audio and medical signal amplification chains. |
| Input Bias Current | 2 pA - enables high-impedance source interfacing (e.g., pH electrodes, photodiode TIA feedback) without significant error. |
Pinout & Package
TLV2773CDGSR is housed in a 10-pin MSOP (DGS) package with exposed thermal pad (not electrically connected). Pin 1 is marked by a beveled edge or molded dot; pin numbering follows standard MSOP convention (counterclockwise from pin 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - rail-to-rail capable, drives loads ≥ 600 Ω with <0.005% THD+N. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node (10¹² Ω), sensitive to layout parasitics. |
| 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 connection shared with all signal returns. |
| 5 | 1SHDN | Active-low shutdown enable for Channel 1 - pulls channel quiescent current to <1 µA when logic low. |
| 6 | VDD | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin. |
| 7 | 2OUT | Output of Channel 2 - independently controllable; identical AC/DC specs to Channel 1. |
| 8 | 2IN− | Inverting input of Channel 2 - electrically isolated from Channel 1 except through shared VDD/GND. |
| 9 | 2IN+ | Non-inverting input of Channel 2 - pin-compatible with standard dual-op-amp routing patterns. |
| 12 | 2SHDN | Active-low shutdown enable for Channel 2 - allows independent power gating of each amplifier. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 100 mV of VDD and GND at 2.2 mA load - eliminates need for level-shifting in single-supply ADC interfaces. |
| Micropower shutdown mode | Reduces per-channel IDD to <1 µA - enables duty-cycled sensing architectures with sub-µA average system current. |
| Low THD+N into 600 Ω | 0.005% at 1 kHz - meets telecom line-driver spectral purity requirements without post-filtering. |
| Extended temperature characterization | Specified over 0°C to 70°C - ensures parametric consistency across commercial-grade industrial control environments. |
| High CMRR and PSRR | 84 dB CMRR and 89 dB PSRR at 25°C - rejects supply ripple and common-mode interference in noisy embedded systems. |
| Low input bias current | 2 pA maximum - prevents voltage error in high-Z sensor circuits (e.g., piezoelectric accelerometers, ion-selective electrodes). |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual CMOS operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462CDR | Lower slew rate (1.6 V/µs), rail-to-rail input/output, higher supply current (550 µA/channel) | Better DC precision (250 µV VIO), but insufficient speed for >100 kHz signal chains | Select when ultra-low offset and rail-to-rail input are prioritized over bandwidth and power. |
| OPA2340UA | Higher slew rate (6 V/µs), rail-to-rail output only, higher supply current (800 µA/channel), no shutdown | Superior THD+N (0.0007%), wider supply range (2.7–5.5 V), but lacks independent channel shutdown | Select when lowest distortion is critical and system-level power management replaces per-channel shutdown. |
Compared with TLV2773CDGSR, TLV2462CDR trades bandwidth and power efficiency for better DC accuracy, while OPA2340UA offers lower distortion and higher drive capability but sacrifices shutdown control and CMOS input advantages - making TLV2773CDGSR optimal for battery-powered, high-speed, low-noise dual-channel sensing where independent power gating is required.

FAQ
What is the operating temperature range for TLV2773CDGSR?
The TLV2773CDGSR is characterized for operation from 0°C to 70°C (C-suffix grade). Its electrical specifications - including input offset voltage, gain-bandwidth, and slew rate - are guaranteed across this full commercial temperature range, ensuring consistent performance in office, factory-floor, and vehicle cabin environments without derating.
Does TLV2773CDGSR support true rail-to-rail input?
No, TLV2773CDGSR provides rail-to-rail *output* swing only. Its input common-mode voltage range extends from GND to VDD − 1.3 V (at 2.7 V supply), meaning the inputs cannot accept signals within 1.3 V of VDD. This limitation requires careful biasing when interfacing with high-side sensors or DAC outputs near the positive rail.
How does the shutdown function work on TLV2773CDGSR?
TLV2773CDGSR features two independent active-low shutdown pins: pin 5 (1SHDN) controls Channel 1, and pin 12 (2SHDN) controls Channel 2. Driving either pin low reduces the respective channel's supply current to <1 µA while placing its output in high-impedance state - enabling selective power gating without affecting the other channel's operation.
Can TLV2773CDGSR drive a 600-Ω load with low distortion?
Yes, TLV2773CDGSR is specifically characterized for 0.005% THD+N when driving a 600-Ω load at 1 kHz with AV = 1. This performance is enabled by its high slew rate (10.5 V/µs) and robust output stage, making it suitable for telecom line drivers, audio codec interfaces, and other applications demanding spectrally clean analog output.
What is the typical input noise voltage of TLV2773CDGSR?
The TLV2773CDGSR has a typical input noise voltage of 17 nV/√Hz at 10 kHz and 12 nV/√Hz at 100 kHz (measured at VDD = 5 V). This low noise floor - combined with 2 pA input bias current - makes it well-suited for amplifying low-level signals from high-impedance sources such as piezoelectric sensors and photodiodes without degrading system SNR.
