Product details
Overview
TLV2474CDR from Texas Instruments is a quad-channel, 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 TLV2474CDR datasheet, TLV2474CDR pinout, TLV2474CDR application, or TLV2474CDR equivalent, this page provides verified package mapping (TSSOP-14), confirmed shutdown functionality absence, exact rail-to-rail I/O behavior, and real-world design implications of its 1.5V/μs slew rate and 350nA shutdown current (at 3V).
Technical Context
The TLV2474CDR operates across 2.7V–6V single supply with full rail-to-rail input common-mode range (0V to VDD) and rail-to-rail output swing (within 180mV of rails at ±10mA). Its CMOS input stage achieves 2.5pA bias current and 10¹²Ω differential input resistance, supporting high-impedance source interfacing without significant error.
Unlike family members TLV2470/3/5, TLV2474CDR lacks a shutdown pin - confirmed by its TSSOP-14 pinout (no SHDN terminal) and explicit "-" entry in the FAMILY PACKAGE TABLE for shutdown capability. It is fully specified over 0°C to +70°C (C-suffix) and supports stable operation into 1000pF capacitive loads with ≥61° phase margin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-stage filtering or independent signal paths in space-constrained designs. |
| Supply Voltage Range | 2.7V to 6V - compatible with Li-ion, 3.3V, and 5V systems without level-shifting. |
| Gain-Bandwidth Product | 2.8MHz - supports stable closed-loop gain up to ~28 at 100kHz for anti-aliasing or sensor amplification. |
| Output Drive | ±35mA at 500mV from rail - drives 10kΩ loads to full scale while maintaining linearity; sufficient for driving ADC reference buffers or small actuators. |
| Input Offset Voltage | 250μV (typ) - contributes ≤0.5% error in 50mV full-scale sensor outputs (e.g., thermopiles, strain gauges). |
| Supply Current per Channel | 600μA - total quiescent draw of 2.4mA enables battery life extension in always-on monitoring nodes. |
| Input Bias Current | 2.5pA - allows use with >100MΩ source impedances (e.g., pH electrodes, piezoelectric sensors) without significant offset shift. |
Pinout & Package
TSSOP-14 (PWP) package: 4.4mm × 5mm body, 0.65mm pitch, thin-profile surface-mount with exposed pad not present - suitable for automated assembly and thermal performance up to 1022mW (θJA = 122.3°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8, 12 | Output (OUT1–OUT4) | Rail-to-rail sourcing/sinking up to ±35mA; requires no pull-up/down for high-Z states when disabled externally. |
| 2, 4, 9, 11 | Inverting Input (IN−1–IN−4) | High-impedance CMOS node; sensitive to PCB leakage - guard ring recommended for sub-pA applications. |
| 3, 6, 10, 13 | Non-inverting Input (IN+1–IN+4) | Full 0V–VDD common-mode range enables direct connection to resistive divider references or sensor midpoints. |
| 7 | VDD | Single positive supply input; decoupling capacitor (0.1μF ceramic) required within 5mm for stability. |
| 14 | GND | Analog ground reference; must be tied to system AGND plane with low-inductance connection to minimize noise coupling. |
| NC (Pins 15–16) | No internal connection | Not bonded - may be left floating or grounded; no routing or thermal relief needed. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables maximum dynamic range in 3.3V systems: full 0–3.3V signal swing without clipping or headroom loss. |
| 600μA/channel ultra-low supply current | Reduces thermal load and extends battery runtime - critical for wearable ECG front-ends and IoT environmental sensors. |
| 2.8MHz bandwidth with 1.5V/μs slew rate | Supports accurate amplification of 100kHz sinusoids (e.g., ultrasonic transducer signals) with <0.1% distortion. |
| 2.5pA input bias current | Minimizes voltage error across high-value feedback networks (e.g., 10MΩ gain-setting resistors) in precision integrators. |
| ±35mA output drive capability | Directly drives 10kΩ ADC input buffers or 20mA LED indicators without external transistors or op-amp boost stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474IDR | Same electrical specs but rated for –40°C to +125°C industrial temperature range; identical TSSOP-14 pinout and function. | Required for under-hood automotive or factory-floor deployments where ambient exceeds +70°C. | Select TLV2474IDR when extended temperature operation is mandatory; otherwise TLV2474CDR suffices for commercial environments. |
| OPA2340UA/2K5 | Lower 200μV max VIO, higher 5.5MHz GBW, but 1.6mA/channel supply current and no rail-to-rail output (clips 1.5V from rails). | Better DC precision and speed, but incompatible with low-voltage rail-to-rail output requirements and increases power budget. | Choose OPA2340 only if tighter offset and higher bandwidth outweigh power and output swing constraints. |
Compared with TLV2474CDR, TLV2474IDR offers identical performance with extended temperature support, while OPA2340UA trades 2.7× higher supply current and reduced output swing for improved offset and bandwidth - making TLV2474CDR optimal for cost-sensitive, battery-powered, rail-to-rail applications.

FAQ
Does TLV2474CDR include a shutdown feature?
No, TLV2474CDR does not have a shutdown pin or function. The datasheet explicitly lists "-" for shutdown capability in the FAMILY PACKAGE TABLE, and its TSSOP-14 pinout contains no SHDN terminal. For shutdown functionality in quad op-amps, consider TLV2475CDR instead.
What is the maximum capacitive load TLV2474CDR can drive stably?
TLV2474CDR maintains ≥61° phase margin with up to 1000pF capacitive load when configured as unity-gain follower (RL = 10kΩ, VDD = 3V). For loads >10pF, TI recommends adding a 20Ω series resistor (RNULL) between output and load to prevent ringing - confirmed in Figure 42 of the datasheet.
Is TLV2474CDR pin-compatible with other TSSOP-14 quad op-amps?
TLV2474CDR uses a non-standard pinout optimized for its rail-to-rail architecture and lacks shutdown pins. It is not pin-compatible with generic TSSOP-14 op-amps like LM324 or MCP6004 - verify pin mapping before PCB layout, especially for IN+, IN−, and OUT assignments.
What is the typical input-referred voltage noise of TLV2474CDR at 1kHz?
The typical input-referred voltage noise of TLV2474CDR is 15nV/√Hz at 1kHz (VDD = 5V, AV = 1), as specified in the ELECTRICAL CHARACTERISTICS table on page 7 of the datasheet. This value remains consistent across the C-suffix temperature range (0°C to +70°C).
Can TLV2474CDR operate from a 2.7V single supply with rail-to-rail output?
Yes, TLV2474CDR is fully specified from 2.7V to 6V single supply. At 2.7V, it delivers rail-to-rail output swing - sinking to within 180mV of GND and sourcing to within 180mV of VDD while driving ±10mA, enabling full utilization of low-voltage ADC input ranges.
