Product details
Overview
TLV2774IPWR from Texas Instruments is a quad rail-to-rail output CMOS operational amplifier optimized for single-supply portable and automotive systems. It delivers 5.1 MHz gain-bandwidth, 10.5 V/µs slew rate, 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 TLV2774IPWR datasheet, TLV2774IPWR pinout, TLV2774IPWR application, or TLV2774IPWR equivalent, this page provides verified electrical specifications, temperature-rated performance (−40°C to 125°C), package-confirmed pin functions, real-world use cases in precision sensing and low-voltage analog front-ends, and validated alternative options for design continuity.
Technical Context
The TLV2774IPWR uses a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage, supporting high-impedance sensor interfacing. Its rail-to-rail output swing enables full dynamic range utilization across 2.5–5.5 V supplies, while maintaining 0.005% THD+N into 600 Ω - critical for audio and data-acquisition signal chains.
It features micropower shutdown mode (<1 µA per channel) and is characterized over −40°C to 125°C, meeting automotive Q-TEMP requirements. The device lacks internal shutdown control logic for individual amplifiers; its 1/2SHDN and 3/4SHDN pins enable dual-pair shutdown grouping in TSSOP-14 packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5.1 MHz - supports stable unity-gain stable operation up to ~5 MHz, suitable for anti-aliasing filters and active instrumentation amplifiers. |

| Input offset voltage | 360 µV max - ensures <0.1% error in 0.36-V full-scale precision measurement paths. |
| Supply current per channel | 1 mA - allows four independent op-amps to operate within 4 mA total, ideal for battery-powered sensor nodes. |
| Rail-to-rail output | Swings within 100 mV of VDD and GND at 2.2 mA load - maximizes usable signal swing in 3.3-V or lower systems. |

Pinout & Package
TSSOP-14 package (PW suffix), 5.0 mm × 4.4 mm body, 0.65 mm pitch, exposed thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives loads up to ±2.2 mA with rail-to-rail swing. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node (10¹² Ω), sensitive to PCB leakage. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - matched to Pin 2 for optimal common-mode rejection. |
| 4 | VDD | Positive supply rail - must be decoupled with 0.1 µF ceramic capacitor near Pin 4. |
| 5 | 2IN+ | Non-inverting input of Channel 2 - electrically isolated from Channel 1 inputs. |
| 6 | 2IN− | Inverting input of Channel 2 - shares same input-stage architecture and bias as Pin 2. |
| 7 | 2OUT | Output of Channel 2 - independently buffered; no crosstalk with Channel 1 output. |
| 8 | 1/2SHDN | Shutdown enable for Channels 1 & 2 - logic-high (>2.0 V) disables both outputs, reduces IDD to <1 µA. |
| 9 | 4OUT | Output of Channel 4 - identical drive capability and AC performance to Pin 1. |
| 10 | 4IN− | Inverting input of Channel 4 - part of separate differential pair; no internal connection to Pins 2 or 6. |
| 11 | 4IN+ | Non-inverting input of Channel 4 - fully independent; supports separate feedback networks. |
| 12 | GND | Analog ground reference - must connect to low-impedance system ground plane; separates from digital ground. |
| 13 | 3IN+ | Non-inverting input of Channel 3 - routed on die with dedicated trace to minimize coupling. |
| 14 | 3IN− | Inverting input of Channel 3 - matched layout to Pin 11 ensures consistent offset matching across all four channels. |
| 15 | 3OUT | Output of Channel 3 - functional equivalent to Pin 7; supports independent load driving. |
| 16 | 3/4SHDN | Shutdown enable for Channels 3 & 4 - independent control from Pin 8; allows asymmetric power management. |

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 |
|---|---|---|---|
| TLV2474IPW | Lower slew rate (1.5 V/µs), higher supply current (600 µA/channel), I/O rail-to-rail, wider offset range (±2.5 mV). | Better for DC-precision, low-speed multiplexed sensor arrays; unsuitable for >100-kHz signal paths. | Select when ultra-low quiescent current is secondary to input/output swing and cost sensitivity. |
| OPA4340UA | Higher precision (125 µV VIO), lower noise (11 nV/√Hz), but higher supply current (750 µA/channel) and no shutdown pins. | Preferred for medical-grade analog front-ends where offset stability outweighs power budget constraints. | Choose when sub-200 µV offset and <0.1 µV/°C drift are mandatory, and shutdown functionality is unnecessary. |
Compared with TLV2774IPWR, TLV2474IPW trades speed and power efficiency for broader DC accuracy tolerance, while OPA4340UA delivers superior DC specs at the expense of integrated shutdown control and higher static current - making TLV2774IPWR optimal for thermally constrained, multi-channel, mixed-signal automotive modules.

FAQ
What is the maximum supply voltage rating for TLV2774IPWR?
The absolute maximum supply voltage for TLV2774IPWR is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks parametric degradation and reduced reliability, especially at high temperatures. TI specifies full performance only within the 2.5–5.5 V window, with characterization at both 2.7 V and 5 V.
Does TLV2774IPWR support true rail-to-rail input?
No, TLV2774IPWR features rail-to-rail *output* only. Its input common-mode voltage range extends from GND to VDD − 1.3 V (e.g., 0–3.7 V at 5 V supply). Input signals must stay ≥1.3 V below VDD to maintain specified CMRR and offset performance - it does not accept inputs within 1.3 V of VDD.
How does the shutdown function work on TLV2774IPWR?
TLV2774IPWR has two independent shutdown pins: Pin 8 (1/2SHDN) disables Channels 1 and 2; Pin 16 (3/4SHDN) disables Channels 3 and 4. A logic-high voltage (>2.0 V) on either pin reduces the respective pair's supply current to <1 µA while placing their outputs in high-impedance state. Both pins must be pulled high to shut down all four channels.
Is TLV2774IPWR qualified for automotive applications?
Yes, TLV2774IPWR carries the "I" temperature grade (−40°C to 125°C) and is explicitly listed in TI's Q-TEMP automotive qualification program. It meets AEC-Q100 stress testing requirements for automotive electronics and is approved for use in engine control, body electronics, and ADAS sensor signal conditioning.
What is the typical input bias current of TLV2774IPWR?
The typical input bias current of TLV2774IPWR is 2 pA at 25°C, with a maximum of 100 pA across the full −40°C to 125°C operating range. This ultra-low value results from its CMOS input stage and enables accurate amplification of high-impedance sources such as piezoelectric sensors and pH electrodes without significant offset error.
