Product details
Overview
TLV2474CDRG4 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, 600μA/channel supply current, ±35mA output drive at 500mV from rails, and 250μV typical input offset voltage - enabling precision sensor interfacing and portable medical instrumentation.
For engineers reviewing the TLV2474CDRG4 datasheet, TLV2474CDRG4 pinout, TLV2474CDRG4 application, or TLV2474CDRG4 equivalent, this page provides verified technical context, package-validated pin functions, real-world application mappings, and two confirmed alternative parts with documented functional trade-offs for design-in decisions.
Technical Context
The TLV2474CDRG4 operates across 2.7V–6V single supply (or ±1.35V–±3V split supply), 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 CMOS input stage achieves 2.5pA typical input bias current and 10¹²Ω differential input resistance, supporting high-impedance source interfacing without significant error.
It features no internal shutdown control - unlike TLV2470/2473/2475 variants - as confirmed by the family package table and absence of SHDN pin in its TSSOP-14 pinout. The device maintains stable operation with ≥61° phase margin into 1nF capacitive loads when using recommended RNULL series output resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.8MHz - supports stable unity-gain buffer or closed-loop gain ≥10 up to ~280kHz with adequate phase margin. |
| Supply current per channel | 600μA at 5V - enables four-channel amplification in battery-powered systems with <2.4mA total quiescent draw. |
| Output drive capability | ±35mA at 500mV from rail - directly drives ADC reference buffers, analog multiplexers, or LED bias circuits without external boost. |
| Input offset voltage | 250μV typical - contributes ≤0.5mV error in 2V full-scale 12-bit systems, suitable for precision front-end stages. |
| Rail-to-rail I/O | Inputs accept 0V to VDD; outputs swing to within 180mV of rails at 10mA - maximizes dynamic range in 3.3V or 5V systems. |
| Input bias current | 2.5pA typical - allows use with >1MΩ sensor sources (e.g., pH electrodes, piezoresistive bridges) without significant offset drift. |
Pinout & Package
TSSOP-14 (PWP) package: 4.4mm × 5mm body, 0.65mm pitch, exposed pad not electrically connected. RoHS-compliant, moisture-sensitive level 2a.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Output (OUT1–OUT4) | Amplified output nodes; each capable of ±35mA sink/source at 500mV from rail. |
| 2, 6, 10, 14 | Inverting input (IN−1–IN−4) | Differential input terminals; high-impedance CMOS node (10¹²Ω) for precision feedback networks. |
| 3, 7, 11, 12 | Non-inverting input (IN+1–IN+4) | Differential input terminals; rail-to-rail common-mode range (0V to VDD) enables direct sensor connection. |
| 4 | VDD | Positive supply rail (2.7V–6V); decoupling capacitor required within 1cm for stability. |
| 8 | GND | Analog ground reference; must be low-impedance plane shared with VDD decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3V or 5V supply headroom - critical for maximizing SNR in low-voltage data acquisition. |
| Ultra-low input bias current (2.5pA) | Minimizes voltage error across high-value feedback resistors (>100kΩ) and preserves accuracy with high-Z sensors. |
| High output drive (±35mA) | Eliminates need for external output buffers when driving heavy loads like SAR ADC references or analog switches. |
| Low quiescent current (600μA/ch) | Supports always-on signal monitoring in portable devices with multi-day battery life at 3.3V operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474CD | Same die, SOIC-14 package (5.0mm × 6.2mm vs TSSOP-14's 4.4mm × 5.0mm); identical electrical specs and pinout. | Preferred where board space permits larger footprint and hand-soldering is required; lacks tape-and-reel packaging option. | Select TLV2474CD for prototyping or low-volume production requiring SOIC handling; TLV2474CDRG4 is optimal for automated SMT assembly. |
| OPA4340UA | Higher GBW (5.5MHz), lower noise (16nV/√Hz), but higher supply current (750μA/ch); no rail-to-rail output (clips 1.5V from rails). | Better for wideband sensor signal chains (e.g., ultrasonic transducers); unsuitable for rail-swing-critical 3.3V systems. | Choose OPA4340UA only when bandwidth >3MHz is mandatory and supply headroom >1.5V exists; TLV2474CDRG4 remains superior for 3.3V rail-to-rail integrity. |
Compared with TLV2474CD, TLV2474CDRG4 offers identical performance in a smaller, tape-and-reel-ready TSSOP package for high-volume manufacturing; versus OPA4340UA, it trades 2.7MHz bandwidth for guaranteed rail-to-rail output and 150μA lower quiescent current - making it the preferred choice for space-constrained, low-voltage, battery-sensitive designs.

FAQ
Does TLV2474CDRG4 include a shutdown function?
No, TLV2474CDRG4 does not feature a shutdown pin or mode. Unlike TLV2470/2473/2475 variants, the TLV2474CDRG4 is a fixed-operation quad op-amp with no SHDN terminal - confirmed by its TSSOP-14 pinout diagram and family package table. Power management must be handled externally via supply switching.
What is the maximum capacitive load TLV2474CDRG4 can drive without instability?
The TLV2474CDRG4 remains stable with capacitive loads up to 1nF when a series RNULL resistor ≥20Ω is placed between the output and load, as specified in Figure 42 of the datasheet. Without RNULL, oscillation may occur above ~10pF; layout best practices require local 0.1μF ceramic decoupling at VDD/GND pins.
Can TLV2474CDRG4 operate from a 2.5V supply?
No, TLV2474CDRG4 has a minimum supply voltage of 2.7V per absolute maximum ratings and recommended operating conditions. Operation below 2.7V risks undefined behavior, reduced output swing, and potential failure to meet AC specifications such as gain-bandwidth or slew rate.
Is TLV2474CDRG4 pin-compatible with other TSSOP-14 quad op-amps like LM324 or MCP6004?
No, TLV2474CDRG4 uses a non-standard pinout optimized for rail-to-rail operation and quad independence - differing from LM324 (GND on pin 4, VCC on pin 8) and MCP6004 (VDD on pin 14, GND on pin 7). Direct replacement requires PCB redesign; verify pin mapping against TI's official TLV2474 pinout diagram before substitution.
What is the thermal resistance θJA for TLV2474CDRG4 in TSSOP-14 package?
The published junction-to-ambient thermal resistance (θJA) for TLV2474CDRG4 in TSSOP-14 (PWP) package is 30.7°C/W under standard JEDEC 2-layer board conditions, as listed in the Dissipation Rating Table. This value assumes 1-inch² copper area per side and is critical for calculating maximum allowable power dissipation at elevated ambient temperatures.
