Product details
Overview
TLV2774IPW from Texas Instruments is a quad rail-to-rail output CMOS operational amplifier optimized for single-supply portable and automotive systems. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, 1 mA per-channel supply current, and operates from 2.5 V to 5.5 V - enabling high-fidelity signal conditioning in ADC driver and telecom line-driver applications.
For engineers reviewing the TLV2774IPW datasheet, TLV2774IPW pinout, TLV2774IPW application, or TLV2774IPW equivalent, key selection criteria include its rail-to-rail output swing into 600-Ω loads (0.005% THD+N), micropower shutdown mode (<1 µA per channel), extended −40°C to 125°C temperature range, and TSSOP-14 package compatibility with space-constrained industrial sensor front-ends.
Technical Context
The TLV2774IPW employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, supporting precision measurement across its full operating temperature range. Its unity-gain-stable architecture achieves 46° phase margin driving 600-Ω loads with 100 pF capacitive load, while maintaining 96 dB CMRR and 89 dB PSRR at 5 V supply.
Designed for low-voltage operation, it features rail-to-rail output swing within 100 mV of each rail at 2.2 mA load, and integrated shutdown control (1/2SHDN and 3/4SHDN pins) enables independent channel power gating - critical for dynamic power management in battery-powered data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typical - supports fast settling for 12-bit ADC sampling at ≥1 MSPS without distortion |
| Gain-Bandwidth Product | 5.1 MHz typical - enables stable unity-gain buffer or G=10 amplification up to 500 kHz |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.0088% gain error in 4.096 V reference buffer applications |
| Supply Current per Channel | 1 mA typical at 5 V - allows four-channel operation under 4.5 mA total, suitable for coin-cell-powered sensors |
| Rail-to-Rail Output | Swings within 100 mV of rails at 2.2 mA - preserves full dynamic range when interfacing with 3.3 V SAR ADCs |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom voice-grade line-driver requirements per ITU-T G.712 |

Pinout & Package
TSSOP-14 package (4.4 mm × 5.0 mm, 0.65 mm pitch), thermally enhanced with exposed pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives external load or next-stage input with rail-to-rail swing |
| 2 | 1IN− | Inverting input of Amp A - high-impedance node (10¹² Ω) for precision feedback networks |
| 3 | 1IN+ | Non-inverting input of Amp A - accepts DC-biased sensor signals or reference voltages |
| 4 | VDD | Positive supply rail - must be decoupled with 100 nF ceramic capacitor near pin |
| 5 | 2IN+ | Non-inverting input of Amp B - isolated from other channels for multi-sensor conditioning |
| 6 | 2IN− | Inverting input of Amp B - supports differential input configuration with matched external resistors |
| 7 | 2OUT | Amplifier B output - independently usable; no crosstalk with Amp A above 60 dB |
| 8 | 1/2SHDN | Shutdown control for Amps A & B - logic-high disables both, reducing IDD to <1 µA |
| 9 | 4OUT | Amplifier D output - identical performance to Amp A; shares same VDD/GND rails |
| 10 | 4IN− | Inverting input of Amp D - routed separately to avoid layout coupling with sensitive analog inputs |
| 11 | 4IN+ | Non-inverting input of Amp D - supports independent biasing for multi-channel transducer interfaces |
| 12 | GND | Analog ground reference - must connect to low-impedance system ground plane |
| 13 | 3IN+ | Non-inverting input of Amp C - enables simultaneous processing of four independent signal paths |
| 14 | 3/4SHDN | Shutdown control for Amps C & D - allows selective channel disable without affecting A/B operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IPW | Lower slew rate (1.6 V/µs), higher supply current (550 µA/channel), I/O rail-to-rail, wider VDD range (2.7–6 V) | Better dc precision (250 µV VIO), but insufficient bandwidth for >100 kHz signal paths | Select TLV2464IPW only when ultra-low offset dominates over speed/power trade-offs |
| OPA4340UA | Higher precision (125 µV VIO), lower noise (8 nV/√Hz), but higher cost and 5.5 mA/channel supply current | Superior for medical instrumentation; unsuitable for battery-powered designs due to 22× higher IDD | Choose OPA4340UA when sub-0.003% gain error and ECG-grade noise performance are mandatory |
Compared with TLV2774IPW, TLV2464IPW trades bandwidth and power efficiency for improved dc accuracy, while OPA4340UA delivers laboratory-grade precision at the expense of 22× higher quiescent current - making TLV2774IPW the optimal balance for cost-sensitive, battery-aware industrial and automotive signal chains.

FAQ
What is the maximum operating supply voltage for TLV2774IPW?
The absolute maximum supply voltage for TLV2774IPW is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation beyond 5.5 V risks parametric degradation and reduced reliability. At 5 V, TLV2774IPW achieves its specified 10.5 V/µs slew rate and 5.1 MHz gain-bandwidth product - values confirmed in the SLOS209G datasheet Section 7.
Does TLV2774IPW support true rail-to-rail input capability?
No, TLV2774IPW 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), as specified in the Recommended Operating Conditions table (Section 5). This limitation requires input signal biasing above GND in single-supply configurations - a design constraint explicitly documented for TLV2774IPW in the TI datasheet.
How does the shutdown functionality work on TLV2774IPW?
TLV2774IPW implements dual independent shutdown controls: Pin 8 (1/2SHDN) disables Amplifiers A and B, while Pin 14 (3/4SHDN) disables Amplifiers C and D. A logic-high voltage (>2.0 V) on either pin reduces the respective pair's supply current to <1.5 µA (typical), as verified in Electrical Characteristics Table (Section 6, IDD(SHDN)). Both pins must be pulled high to fully disable all four channels.
What is the thermal performance of TLV2774IPW in TSSOP-14 package?
In the TSSOP-14 (PW) package, TLV2774IPW has a power dissipation rating of 700 mW at TA ≤ 25°C, derating linearly at 5.6 mW/°C above 25°C - yielding 448 mW at 70°C and 140 mW at 125°C (Dissipation Rating Table, Section 5). This thermal profile supports continuous operation in sealed automotive enclosures without forced airflow, provided PCB copper area meets TI's layout guidelines for PW packages.
Can TLV2774IPW drive a 600-Ω load with low distortion at 1 kHz?
Yes, TLV2774IPW delivers 0.005% THD+N when driving a 600-Ω load at 1 kHz and AV = 1, as measured at VDD = 5 V (Operating Characteristics Table, Section 9). This performance meets ITU-T G.712 voice-band line driver specifications and is enabled by its 10.5 V/µs slew rate and rail-to-rail output stage - both validated across the −40°C to 125°C temperature range per the TLV2774IPW characterization data.
