Product details
Overview
TLV2474IPWP 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 across 2.7V–6V operation - enabling precision sensor front-ends and portable medical instrumentation.
For engineers reviewing the TLV2474IPWP datasheet, TLV2474IPWP pinout, TLV2474IPWP application, or TLV2474IPWP equivalent, this page provides verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options for battery-powered, space-constrained analog signal chains requiring rail-to-rail swing and shutdown control.
Technical Context
The TLV2474IPWP implements a CMOS input stage with rail-to-rail common-mode input range (0V to VDD) and rail-to-rail output swing (within 180mV of rails at ±10mA), supporting full dynamic range in 3V systems. Its 2.8MHz unity-gain bandwidth and 1.5V/μs slew rate enable stable closed-loop operation up to 10kHz with 10kΩ load and 1000pF capacitive feedback.
It features independent channel shutdown control via dedicated SHDN pins (pins 3/4 and 11/12), reducing quiescent current to 1000nA/channel at 5V while placing outputs in high-impedance state - critical for power-gated multi-channel data acquisition where channel-by-channel enable/disable is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - supports direct connection to Li-ion (3.7V), USB (5V), or dual-cell alkaline (3V) supplies without regulation. |
| Gain-Bandwidth Product | 2.8MHz - enables stable unity-gain buffer or gain-of-10 amplification up to ~280kHz with phase margin >61°. |
| Input Bias Current | 2.5pA (typ) - allows high-impedance sensor interfaces (e.g., pH electrodes, piezoresistive bridges) without significant DC error. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 10kΩ loads to full rail while sourcing/sinking >3× typical op-amp current for active filters or DAC buffers. |
| Shutdown Current | 1000nA/channel at 5V - reduces total system standby power to <4μA for all four channels, extending battery life in portable devices. |
| Input Offset Voltage | 250μV (typ) - ensures <0.01% gain error in 24-bit ADC front-ends with 5V full-scale reference. |
| Common-Mode Rejection | 84dB (typ at 5V) - suppresses supply ripple and shared-noise coupling in multi-channel simultaneous-sampling systems. |
Pinout & Package
TSSOP-14 package (PWP), 5.0mm × 4.4mm × 1.2mm body, 0.65mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | OUTx | Amplifier output terminals - each capable of ±35mA drive into 500mV headroom; requires local 100nF bypass near VDD (pin 14). |
| 2, 6, 10, 12 | IN−x | Inverting inputs - high-impedance CMOS nodes; sensitive to PCB leakage; guard ring recommended for sub-pA bias applications. |
| 3, 4, 11, 12 | SHDNx | Active-low shutdown controls for channels 1/2 (pins 3/4) and 3/4 (pins 11/12); logic threshold VIH = 2V, VIL = 0.8V referenced to GND. |
| 7, 8, 14 | GND | Ground reference for all channels and shutdown logic - must be low-inductance plane; separate analog/digital ground not required. |
| 14 | VDD | Positive supply input - accepts 2.7V–6V; decoupling capacitor (0.1μF ceramic + 4.7μF tantalum) mandatory at pin. |

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 die, SOIC-14 package; no shutdown pins; 0°C to +70°C temp range; 600μA/channel IDD unchanged. | Lacks per-channel shutdown - unsuitable for duty-cycled multi-sensor systems requiring selective channel disable. | Select when board space permits SOIC and shutdown functionality is unnecessary; lower cost for commercial-temp applications. |
| OPA4340UA | Higher 5.5MHz GBW, 1.5mV max VIO, 750μA/channel IDD; no shutdown; SOIC-14 only; specified to +125°C. | Superior AC performance but higher power and no shutdown - better for wideband active filters, worse for ultra-low-power battery operation. | Select when bandwidth >3MHz is required and shutdown is not needed; verify thermal design due to higher dissipation. |
Compared with TLV2474IPWP, TLV2474CDR removes shutdown capability and relaxes temperature rating, while OPA4340UA trades 2.5× higher supply current for 2× bandwidth and tighter offset - making TLV2474IPWP optimal for space-constrained, battery-sensitive designs needing selective channel power control.

FAQ
What is the maximum capacitive load the TLV2474IPWP can drive without instability?
The TLV2474IPWP remains stable with up to 1000pF capacitive load when configured as unity-gain follower with 10kΩ load, per Figure 18–19 in the datasheet. For loads exceeding 10pF, TI recommends adding a 20Ω series resistor (RNULL) between output and capacitive node to maintain phase margin above 61° - a requirement confirmed in Application Information section "Driving a Capacitive Load".
Does the TLV2474IPWP support true single-supply operation down to 2.7V?
Yes, the TLV2474IPWP is fully specified from 2.7V to 6V, including rail-to-rail input common-mode range (0V to VDD) and output swing within 180mV of both rails at ±10mA. Electrical characteristics tables explicitly list test conditions at VDD = 3V and VDD = 5V, confirming functional operation at minimum supply.
How does shutdown operation affect output impedance and signal integrity in the TLV2474IPWP?
When TLV2474IPWP enters shutdown (SHDN pin low), its output transitions to high-impedance state with isolation >60dB up to 1MHz (Figure 35–36), preventing loading of downstream circuitry. Output leakage remains below 1nA, preserving signal integrity in multiplexed or shared-bus configurations - verified in Shutdown Forward/Reverse Isolation graphs.
Can the TLV2474IPWP be used in inverting amplifier configurations with gain ≥10?
Yes, the TLV2474IPWP maintains stability in inverting configurations with gain ≥10 when using standard compensation techniques. At AV = –10, settling time is 1.7μs to 0.01% with 56pF load (Table, page 7), and phase margin exceeds 68° with 1000pF load (Figure 19), confirming robust closed-loop behavior per datasheet operating characteristics.
What is the thermal performance of the TLV2474IPWP in TSSOP-14 (PWP) package?
The TLV2474IPWP in TSSOP-14 has θJA = 30.7°C/W and θJC = 2.07°C/W (Dissipation Rating Table, page 4). At maximum 4.07W power rating and 125°C junction limit, it sustains continuous operation at ambient up to +85°C with minimal heatsinking - validated across –40°C to +125°C operating range in Recommended Operating Conditions.
