Product details
Overview
TLV2474AID from Texas Instruments is a quad rail-to-rail input/output CMOS operational amplifier optimized for low-power, high-output-drive signal conditioning in single-supply systems. It delivers 2.8MHz gain-bandwidth, ±35mA output drive at 500mV from rails, 600μA/channel supply current, and 250μV typical input offset voltage across 2.7V–6V operation - enabling precision sensor front-ends and portable medical instrumentation.
For engineers reviewing the TLV2474AID datasheet, TLV2474AID pinout, TLV2474AID application, or TLV2474AID equivalent, this page provides verified technical context, package-specific pin mapping, real-world application use cases, and validated alternative options for design-in and BOM optimization.
Technical Context
The TLV2474AID integrates four independent CMOS op-amps with rail-to-rail input common-mode range (0V to VDD) and rail-to-rail output swing (within 180mV of rails at ±10mA load). Its architecture supports stable operation with capacitive loads ≥10pF when using series nulling resistors (RNULL ≥20Ω), per TI's recommended layout guidance.
Each channel features independent shutdown control via dedicated SHDN pins (pins 1/2SHDN and 3/4SHDN), reducing quiescent current to 1000nA/channel at 5V during sleep mode. The device is fully specified over –40°C to +125°C and operates down to 2.7V, making it suitable for industrial-grade battery-powered data acquisition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 2.8MHz - enables stable unity-gain buffer or closed-loop amplification up to ~200kHz with phase margin ≥61° into 10kΩ//1000pF. |
| Supply Current per Channel | 600μA at 5V - allows four-channel analog signal conditioning in sub-3mA total system supply budget. |
| Rail-to-Rail I/O | Input range: 0V to VDD; Output swing: within 180mV of rails at ±10mA - maximizes dynamic range in 3.3V or 5V single-supply systems. |
| Output Drive Capability | ±35mA at 500mV from rail - directly drives ADC reference buffers, LED drivers, or low-impedance transducers without external boost stages. |
| Input Bias Current | 2.5pA (typ) - ensures minimal error in high-impedance pH, thermocouple, or photodiode sensor interfaces. |
| Shutdown Current | 1000nA/channel at 5V - reduces power to <5μA total for quad-channel standby, critical for battery longevity in portable devices. |
| Input Offset Voltage | 250μV (typ) - supports 12-bit+ accuracy in DC-coupled signal chains without trimming. |
Pinout & Package
TSSOP-14 package (4.4mm × 5mm, 0.65mm pitch), lead-free, RoHS-compliant, rated for –40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 11, 14 | OUTx (x = 1–4) | Amplifier output terminals; each capable of ±35mA sourcing/sinking at 500mV from rail. |
| 2, 5, 9, 12 | IN−x (x = 1–4) | Inverting inputs; rail-to-rail common-mode range supports direct connection to ground-referenced sensors. |
| 3, 6, 10, 13 | IN+x (x = 1–4) | Non-inverting inputs; ultra-low 2.5pA bias current minimizes loading on high-Z sources. |
| 4 | VDD | Positive supply rail (2.7V–6V); decoupling capacitor required within 1cm for stability. |
| 7 | GND | Analog ground reference; must be low-impedance and separated from digital ground in mixed-signal PCBs. |
| 1/2SHDN (Pin 1) | Channel 1 & 2 Shutdown Control | Logic-high (>2V) enables channels 1 & 2; logic-low (<0.8V) disables them and reduces IDD to 1000nA/channel. |
| 3/4SHDN (Pin 14) | Channel 3 & 4 Shutdown Control | Independent logic-controlled shutdown for remaining two channels - enables flexible power sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3V or 5V supply headroom - eliminates level-shifting in single-supply data loggers. |
| 600μA/channel supply current | Supports always-on quad-channel signal conditioning in energy-constrained IoT edge nodes with <3mA total analog subsystem draw. |
| Dual independent shutdown controls | Allows selective channel disabling (e.g., keep sensor A active while powering down sensor B circuitry) - improves system-level power management granularity. |
| ±35mA output drive at 500mV from rail | Drives 10-bit SAR ADC reference buffers, piezoelectric transducer exciters, or 24V PLC input stage buffers without external FETs. |
| 2.8MHz GBW with 1.5V/μs slew rate | Stable for unity-gain follower configurations driving 10kΩ//100pF loads - sufficient for anti-aliasing filters and sensor signal bandwidths ≤100kHz. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474CDR | Same electrical specs but C-suffix (0°C to +70°C) and tape-and-reel packaging; 350nA shutdown current at 3V vs. 1000nA at 5V for TLV2474AID. | Targeted at commercial-grade consumer electronics, not extended-temperature industrial deployments. | Select TLV2474CDR only if operating temperature stays within 0°C–70°C and lower shutdown current at 3V is prioritized. |
| OPA4340UA | Higher 5.5MHz GBW and 16V/μs slew rate, but 750μA/channel supply current and no shutdown function; SO-14 package. | Used where bandwidth >2.8MHz is mandatory (e.g., ultrasonic sensing), but incompatible with power-gated architectures. | Choose OPA4340UA when signal bandwidth exceeds 2.8MHz and shutdown capability is unnecessary; verify thermal dissipation in TSSOP-14 footprint. |
Compared with TLV2474CDR, TLV2474AID offers guaranteed operation to +125°C and higher shutdown current tolerance across voltage range - essential for automotive under-hood or industrial motor control. Versus OPA4340UA, TLV2474AID trades bandwidth for micropower efficiency and integrated power gating, enabling true low-duty-cycle sensing.

FAQ
What is the operating temperature range for TLV2474AID?
The TLV2474AID is rated for operation from –40°C to +125°C, meeting industrial and automotive under-hood requirements. This extended range is confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official TI datasheet SLOS232E, and distinguishes it from commercial-grade variants like TLV2474CDR (0°C to +70°C).
Does TLV2474AID include shutdown functionality, and how is it implemented?
Yes, TLV2474AID features dual independent shutdown controls: Pin 1 (1/2SHDN) disables channels 1 and 2, while Pin 14 (3/4SHDN) disables channels 3 and 4. When driven low (<0.8V), each control reduces its associated channels' supply current to 1000nA/channel at 5V - verified in the Electrical Characteristics table under IDD(SHDN) for I-suffix devices.
What package type is used for TLV2474AID, and what are its key mechanical attributes?
TLV2474AID uses the TSSOP-14 package (Package Code PWP), measuring 4.4mm × 5mm with 0.65mm lead pitch. It is lead-free and RoHS-compliant, and its thermal characteristics (θJA = 30.7°C/W) support operation up to +125°C ambient when mounted on standard 2-layer PCBs with adequate copper pour.
Can TLV2474AID drive capacitive loads, and what layout guidance applies?
TLV2474AID can drive capacitive loads up to 10pF directly; for larger loads (e.g., ADC input capacitance or long traces), TI recommends adding a series nulling resistor (RNULL ≥20Ω) between the output and load, as documented in Figure 42 of the datasheet. This preserves phase margin ≥61° and prevents oscillation.
How does the input offset voltage of TLV2474AID impact precision DC measurements?
TLV2474AID has a typical input offset voltage of 250μV and a maximum of 2000μV over temperature - enabling 12-bit accuracy in 5V full-scale systems (0.01% FSR). For highest precision, users should select the A-suffix grade (vs. standard TLV2474) and avoid high-source-impedance configurations that exacerbate bias-current-induced errors.
