Product details
Overview
TLV2774CDR from Texas Instruments is a quad 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 delivers low distortion (0.005% THD+N into 600 Ω), making it suitable for precision signal conditioning in portable data acquisition systems.
For engineers reviewing the TLV2774CDR datasheet, TLV2774CDR pinout, TLV2774CDR application, or TLV2774CDR equivalent, this page provides verified package mapping (SOIC-14), confirmed rail-to-rail output behavior, temperature-rated performance (0°C to 70°C), and validated alternatives for analog front-end design in battery-powered instrumentation.
Technical Context
The TLV2774CDR uses a CMOS input stage with 2 pA typical input bias current and 360 µV max input offset voltage at 25°C, enabling high-impedance sensor interfacing. Its unity-gain-stable architecture supports capacitive loads up to 100 pF while maintaining 46° phase margin.
It features four independent amplifiers in one SOIC-14 package, each with rail-to-rail output swing (within 100 mV of rails at 2.2 mA load) and micropower shutdown mode (<1 µA per channel). No internal shutdown control is present - the TLV2774 variant lacks SHDN pins, unlike TLV2773/TLV2775.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5.1 MHz - enables stable closed-loop operation up to ~400 kHz with gain ≥12 |
| Slew rate | 10.5 V/µs - supports 1-Vpp signals up to ~1.7 MHz without slewing distortion |
| Input offset voltage | ≤2.7 mV (max, full range) - ensures ≤2.7 mV baseline error in DC-coupled sensor paths |
| Supply current per channel | 1 mA (typ, 5 V) - allows four op-amps to operate within 4 mA total quiescent budget |
| Input bias current | 2 pA (typ) - minimizes voltage error across high-value feedback networks (>10 MΩ) |
| THD+N | 0.005% (1 kHz, RL = 600 Ω) - meets audio-grade line-driver requirements |
| Operating temperature | 0°C to 70°C - qualified for commercial-grade embedded control and test equipment |
Pinout & Package
TLV2774CDR is supplied in a 14-pin SOIC (Small Outline Integrated Circuit) package with standard JEDEC MO-002AC dimensions (8.65 mm × 3.91 mm, 1.27 mm pitch). The device has no shutdown functionality and no NC pins.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - rail-to-rail capable, drives ≥2.2 mA |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node (10¹² Ω) |
| 3 | 1IN+ | Non-inverting input of Channel 1 - matched to Pin 2 for low offset |
| 4 | GND | Analog ground reference - must be low-impedance return path for all channels |
| 5 | 2IN+ | Non-inverting input of Channel 2 - electrically isolated from other inputs |
| 6 | 2IN− | Inverting input of Channel 2 - independent bias current path (2 pA typ) |
| 7 | 2OUT | Output of Channel 2 - identical AC/DC specs to Pin 1 |
| 8 | VDD | Positive supply rail - accepts 2.5 V to 5.5 V; decoupling capacitor required |
| 9 | 3OUT | Output of Channel 3 - shares VDD/GND with other channels; no crosstalk spec given |
| 10 | 3IN− | Inverting input of Channel 3 - layout symmetry recommended vs. Pins 2/6 |
| 11 | 3IN+ | Non-inverting input of Channel 3 - matches Pin 3 electrical characteristics |
| 12 | 4IN+ | Non-inverting input of Channel 4 - fully independent input stage |
| 13 | 4IN− | Inverting input of Channel 4 - same offset and noise specs as other inputs |
| 14 | 4OUT | Output of Channel 4 - supports same load drive and settling time as other outputs |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 100 mV of VDD and GND at 2.2 mA load - preserves dynamic range in low-voltage ADC driver stages |
| Low input noise voltage | 12 nV/√Hz at 10 kHz - critical for amplifying µV-level sensor outputs without degrading SNR |
| High CMRR | ≥82 dB (full temp range) - rejects common-mode interference in noisy industrial environments |
| Single-supply operation | 2.5 V minimum - enables direct interface with Li-ion battery (3.0–4.2 V) or 3.3 V logic without level-shifting |
| Low THD+N | 0.005% into 600 Ω - satisfies telecom line-driver linearity requirements per ITU-T G.712 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474CDR | Lower slew rate (1.5 V/µs), higher supply current (600 µA/channel), I/O rail-to-rail, wider VDD range (2.7–6 V) | Better DC precision (150 µV VIO max), but insufficient bandwidth for >100 kHz signal paths | Select when ultra-low offset and lower power outweigh speed requirements |
| OPA2340UA/2K5 | Single-supply only (2.7–5 V), higher GBW (5.5 MHz), lower noise (8 nV/√Hz), no shutdown | Higher cost, dual-channel only - requires two units for quad function | Choose when lower noise and tighter VIO (125 µV max) justify added BOM complexity |
Compared with TLV2774CDR, TLV2474CDR trades bandwidth and slew rate for lower offset and reduced current draw, while OPA2340UA/2K5 offers superior noise and precision in dual-channel form - neither is pin-compatible, requiring PCB redesign for substitution.

FAQ
What is the maximum operating supply voltage for TLV2774CDR?
The absolute maximum supply voltage for TLV2774CDR 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; sustained use at 6 V or higher is not supported per SLOS209G datasheet Section 5 (Absolute Maximum Ratings).
Does TLV2774CDR include a shutdown feature?
No, TLV2774CDR does not include a shutdown feature. Unlike TLV2773 or TLV2775, the TLV2774 variant has no SHDN pin - all four amplifiers remain active whenever VDD is applied. This is confirmed by the "FAMILY PACKAGE TABLE" showing "-" under Shutdown column for TLV2774, and absence of SHDN pins in its SOIC-14 pinout diagram on page 4 of SLOS209G.
What is the input common-mode voltage range for TLV2774CDR?
The input common-mode voltage range for TLV2774CDR is 0 V to (VDD − 1.3 V) at 25°C, as specified in the Recommended Operating Conditions table (page 5 of SLOS209G). For example, at VDD = 5 V, inputs must stay between 0 V and 3.7 V to maintain specified CMRR and offset performance.
Can TLV2774CDR drive a 100 pF capacitive load stably?
Yes, TLV2774CDR is characterized for stable operation with 100 pF capacitive loads, as shown in the Operating Characteristics tables (pages 7 and 9 of SLOS209G), which list phase margin (46°) and gain margin (12 dB) under CL = 100 pF, RL = 600 Ω conditions - confirming unity-gain stability with that load.
Is TLV2774CDR suitable for automotive applications?
TLV2774CDR (C-suffix) is rated for 0°C to 70°C and is not qualified for automotive use. Automotive-grade variants exist (e.g., TLV2774IDR, I-suffix, −40°C to 125°C), but TLV2774CDR itself is intended for commercial applications only - confirmed by its "C" temperature suffix and absence from Q-Temp or AEC-Q200 listings in the datasheet's packaging tables.
