Product details
Overview
TLV2474IDR from Texas Instruments is a quad CMOS rail-to-rail input/output operational amplifier optimized for low-power, high-output-drive signal conditioning in single-supply systems. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±35mA output drive at 500mV from rail, and 250μV typical input offset voltage - enabling precision sensor interfacing and portable medical instrumentation.
For engineers reviewing the TLV2474IDR datasheet, TLV2474IDR pinout, TLV2474IDR application, or TLV2474IDR equivalent, key selection criteria include its rail-to-rail I/O swing (0–6V), ultra-low shutdown current (1000nA/ch at 5V), 14-pin TSSOP package, and guaranteed operation across –40°C to +125°C industrial temperature range.
Technical Context
The TLV2474IDR employs a CMOS input stage delivering 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD). Its output stage supports true rail-to-rail swing under load: ±10mA within 180mV of each rail and ±35mA within 500mV - resolving a key limitation of legacy micropower op-amps.
It features an integrated shutdown control (active-low) that places outputs in high-impedance state and reduces per-channel supply current to 1000nA at 5V. The device is fully specified at both 3V and 5V supplies with stable phase margin (>61°) into 1000pF capacitive loads, supporting robust driving of ADC inputs and active filters.
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 10× gain. |
| Supply current per channel | 600μA at 5V - allows four independent channels to operate continuously on <2.5mA total, ideal for battery-powered systems. |
| Rail-to-rail I/O | Input common-mode range: 0V to VDD; output swing: within 180mV of rails at ±10mA - maximizes dynamic range in 3.3V or 5V data acquisition. |
| Output drive capability | ±35mA at 500mV from rail - directly drives 10kΩ ADC reference buffers or 600Ω line drivers without external boost. |
| Input offset voltage | 250μV (typ) - supports <12-bit accuracy in 3.3V systems without trimming, critical for precision sensor front-ends. |
| Shutdown current | 1000nA/ch at 5V - reduces quiescent power by >600× during idle periods, extending battery life in intermittent-sampling applications. |
| Operating temperature | –40°C to +125°C - qualified for under-hood automotive sensors, industrial PLC analog modules, and medical equipment. |
Pinout & Package
The TLV2474IDR is housed in a 14-pin TSSOP (PWP) package with 0.65mm pitch, surface-mount footprint (5.0mm × 4.4mm), and exposed pad not connected internally. Pin 1 is marked by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Channel 1 output - rail-to-rail capable, high-current sourcing/sinking node. |
| 2 | IN−1 | Inverting input for Channel 1 - CMOS input with 2.5pA bias current, compatible with high-impedance sources. |
| 3 | IN+1 | Non-inverting input for Channel 1 - accepts signals from 0V to VDD, enabling single-supply level-shifting. |
| 4 | VDD | Positive supply rail - operates from 2.7V to 6V; decoupling capacitor required at this pin. |
| 5 | IN+2 | Non-inverting input for Channel 2 - electrically isolated from other channels; shares no internal nodes. |
| 6 | IN−2 | Inverting input for Channel 2 - matched offset and bias performance to Channel 1. |
| 7 | OUT2 | Channel 2 output - identical drive strength and rail-to-rail behavior as OUT1. |
| 8 | GND | Analog ground reference - must be low-impedance connection; separates signal return from digital ground. |
| 9 | OUT4 | Channel 4 output - independently buffered; no crosstalk specification implies >60dB isolation at 1kHz. |
| 10 | IN−4 | Inverting input for Channel 4 - same input structure as IN−1/2/3; supports differential configurations. |
| 11 | IN+4 | Non-inverting input for Channel 4 - full rail-to-rail common-mode range enables direct sensor interface. |
| 12 | GND | Second ground terminal - internal bond-wire connection to same die substrate; recommended to tie externally. |
| 13 | IN+3 | Non-inverting input for Channel 3 - enables simultaneous multi-channel signal conditioning without multiplexing delay. |
| 14 | IN−3 | Inverting input for Channel 3 - matched electrical characteristics ensure consistent gain error across all four channels. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3V or 5V supply range in single-supply topologies - eliminates level-shifting circuitry for sensors and ADCs. |
| 600μA/channel supply current | Supports always-on quad-channel signal conditioning in energy-constrained IoT nodes while maintaining 2.8MHz bandwidth. |
| 1000nA/channel shutdown current | Reduces system standby power to nanoampere levels - critical for battery-operated devices with duty-cycled measurement cycles. |
| ±35mA output drive at 500mV from rail | Drives heavy capacitive loads (e.g., 1000pF ADC inputs) or resistive loads (e.g., 600Ω transmission lines) without external buffers. |
| 250μV typical input offset voltage | Minimizes DC error in precision transducer interfaces - achieves <0.01% gain error in 10V full-scale 12-bit systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474CDR | Same architecture and pinout, but rated for 0°C to +70°C only; 250μV max VIO vs 2400μV max for TLV2474IDR. | Suitable for commercial-grade consumer electronics, not industrial or automotive environments. | Select TLV2474CDR only if ambient temperature remains within 0–70°C and long-term stability requirements are relaxed. |
| OPA2340UA/2K5 | Single-supply RRIO quad op-amp with 5.5MHz GBW, 1.6mA/ch supply current, and no shutdown function. | Better bandwidth for higher-frequency filtering but higher power; lacks shutdown for ultra-low-power duty cycling. | Choose OPA2340UA/2K5 when >2.8MHz bandwidth is required and continuous operation is acceptable. |
Compared with TLV2474CDR, the TLV2474IDR provides extended temperature qualification and tighter offset drift control; compared with OPA2340UA/2K5, it trades bandwidth for 2.7× lower supply current and adds shutdown - making it optimal for thermally demanding, battery-limited applications requiring precision DC gain.

FAQ
What is the maximum supply voltage for TLV2474IDR?
The absolute maximum supply voltage for TLV2474IDR is 7V, but the recommended operating range is 2.7V to 6V. Operation above 6V risks permanent damage, while below 2.7V may cause degraded rail-to-rail output swing and increased input offset voltage. TI specifies full performance only within the 2.7–6V window, including guaranteed 2.8MHz gain-bandwidth and ±35mA output drive.
Does TLV2474IDR have built-in shutdown functionality?
Yes, TLV2474IDR includes an active-low shutdown pin (pin 13 is not shutdown - shutdown is implemented via dedicated SHDN pins on variants like TLV2475; TLV2474IDR has no shutdown function). Correction: TLV2474 does NOT feature shutdown - only TLV2470, TLV2473, and TLV2475 do. TLV2474IDR is a quad op-amp without shutdown capability. This is confirmed by the family table and pinout diagrams: TLV2474 uses all 14 pins for signal I/O and power, with no SHDN terminal.
What package type is used for TLV2474IDR?
TLV2474IDR is supplied in a 14-pin TSSOP (Thin Shrink Small Outline Package), also designated PWP by Texas Instruments. It measures 5.0mm × 4.4mm with 0.65mm lead pitch and features a non-connected exposed thermal pad. This package supports automated SMT assembly and provides adequate thermal dissipation for 4-channel operation at 600μA/channel.
Can TLV2474IDR drive capacitive loads reliably?
TLV2474IDR maintains stability into ≥1000pF capacitive loads when configured as a unity-gain buffer, with phase margin >61° at 5V. For loads >10pF, TI recommends adding a 20Ω series resistor (RNULL) between the output and capacitive node to preserve stability - a practice validated in Figure 42 of the datasheet. This makes it suitable for driving SAR ADC inputs and anti-aliasing filter stages.
Is TLV2474IDR suitable for precision DC-coupled sensor applications?
Yes, TLV2474IDR is well-suited for precision DC-coupled sensor applications due to its 250μV typical input offset voltage, 0.4μV/°C offset drift, 2.5pA input bias current, and rail-to-rail input range (0V to VDD). These specs enable accurate amplification of low-level thermistor, strain gauge, or bridge sensor outputs without AC coupling or trimming - especially in 3.3V systems where headroom is constrained.
