Product details
Overview
TLV2474IPWPR 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, ±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 interfacing and portable medical front-ends.
For engineers reviewing the TLV2474IPWPR datasheet, TLV2474IPWPR pinout, TLV2474IPWPR application, or TLV2474IPWPR equivalent, this page provides verified functional specifications, TSSOP-14 package layout, real-world use cases in battery-powered data acquisition, and validated alternative op-amps with documented performance trade-offs.
Technical Context
The TLV2474IPWPR employs a CMOS input stage delivering 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD), supporting true single-supply operation down to 2.7V. Its output stage swings within 180mV of both rails under 10mA load and sustains ±35mA at 500mV from rails - resolving key limitations of legacy micropower amplifiers.
It integrates no internal shutdown control: unlike TLV2470/2473/2475 variants, TLV2474 lacks a SHDN pin and operates continuously. This simplifies biasing but excludes ultra-low-quiescent modes - confirmed by absence of IDD(SHDN) specification and omission from shutdown-capable device table in SLOS232E.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 4 independent amplifiers - enables compact multi-signal conditioning without board-level duplication. |
| Supply Voltage Range | 2.7V to 6V - supports direct connection to Li-ion (3.0–4.2V), 3.3V logic, and 5V legacy rails without level-shifting. |
| Gain-Bandwidth Product | 2.8MHz - sufficient for anti-aliasing filters, sensor amplification up to ~200kHz, and closed-loop stability with 10kΩ/100pF loads. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 100Ω loads directly, eliminates need for external buffers in DAC output stages or LED drivers. |
| Input Offset Voltage | 250μV (typ) - enables <1 LSB error in 12-bit ADC interfaces with gain ≤100, critical for precision instrumentation. |
| Supply Current per Channel | 600μA - total 2.4mA quiescent draw allows continuous operation in always-on sensor nodes with >1-year battery life (e.g., CR2032). |
| Input Bias Current | 2.5pA - preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor interfaces without leakage-induced drift. |
Pinout & Package
TSSOP-14 (PWP) package: 4.4mm × 5.0mm body, 0.65mm pitch, exposed pad not electrically connected. Pin 1 marked by beveled edge or molded dot; pin numbering counterclockwise from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - rail-to-rail swing supports full dynamic range in single-supply configurations. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node; requires matched trace routing to minimize offset drift. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - accepts signals from 0V to VDD; enables true DC-coupled sensor inputs. |
| 4 | VDD | Positive supply - decoupling capacitor (0.1μF ceramic) required within 5mm for stable high-frequency operation. |
| 5 | 2IN+ | Non-inverting input of Channel 2 - isolated from Channel 1 inputs to prevent crosstalk in multi-channel filtering. |
| 6 | 2IN− | Inverting input of Channel 2 - symmetric layout with Pin 2 ensures matched parasitics for differential pair accuracy. |
| 7 | 2OUT | Output of Channel 2 - independently buffered; no internal connection to other outputs (no shared output stage). |
| 8 | GND | Analog ground reference - must connect to low-impedance PCB ground plane; separate from digital ground if mixed-signal. |
| 9 | 3OUT | Output of Channel 3 - identical electrical specs to Pins 1 and 7; supports simultaneous multi-path signal processing. |
| 10 | 3IN− | Inverting input of Channel 3 - pinout symmetry with Channels 1–2 simplifies layout reuse across all four channels. |
| 11 | 3IN+ | Non-inverting input of Channel 3 - enables identical configuration as Channel 1 (e.g., unity-gain buffer for reference voltage). |
| 12 | 4IN+ | Non-inverting input of Channel 4 - dedicated pin avoids multiplexing delays; critical for real-time multi-sensor sync. |
| 13 | 4IN− | Inverting input of Channel 4 - matches impedance of Pin 12; maintains channel-to-channel gain matching within 0.1%. |
| 14 | 4OUT | Output of Channel 4 - fully independent; allows four concurrent analog functions (e.g., 4-channel ECG front-end). |
Key Features

| ±35mA high output drive | Directly drives 100Ω loads (e.g., transmission lines, relay coils) without external transistors - cuts BOM cost and board area. |
| 2.5pA input bias current | Minimizes voltage error in high-Z sensor circuits (e.g., 10MΩ thermistor networks) - keeps offset drift below 25μV over temperature. |
| 250μV typical input offset voltage | Supports 12-bit precision in gain-of-100 configurations - eliminates need for manual trimming or auto-zero circuitry in production. |
| 2.8MHz gain-bandwidth product | Stable at unity gain with 100pF capacitive loads - enables robust anti-aliasing filter design without external compensation components. |

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 die, C-temp (0°C to +70°C) grade; identical electrical specs except wider VIO max (2400μV vs. 2000μV for I-grade). | Not rated for extended industrial (-40°C to +125°C) environments - unsuitable for automotive under-hood or factory-floor deployments. | Select TLV2474CDR only for cost-sensitive commercial applications where ambient temperature stays within 0–70°C. |
| OPA2333PWR | Zero-drift architecture: 0.02μV/°C offset drift vs. TLV2474IPWPR's 0.4μV/°C; higher 350μA/channel supply current; 350kHz GBW. | Superior DC precision for long-term drift-critical applications (e.g., weigh scales), but insufficient bandwidth for >10kHz sensor signals. | Choose OPA2333PWR when offset drift dominates error budget; retain TLV2474IPWPR for bandwidth-constrained, low-power, wide-temp designs. |
Compared with TLV2474CDR, TLV2474IPWPR offers guaranteed -40°C to +125°C operation and tighter offset voltage limits, making it suitable for harsh environments; versus OPA2333PWR, TLV2474IPWPR trades zero-drift precision for 8× higher bandwidth and lower power - optimizing for dynamic signal fidelity over ultra-stable DC gain.

FAQ
Does TLV2474IPWPR include a shutdown function?
No, TLV2474IPWPR does not have a shutdown pin or mode. Unlike TLV2470/2473/2475 variants, the TLV2474 family omits the SHDN terminal entirely - confirmed by its absence in the TSSOP-14 pinout diagram and lack of IDD(SHDN) specifications in the SLOS232E datasheet. TLV2474IPWPR operates continuously whenever powered.
What is the maximum capacitive load TLV2474IPWPR can drive stably?
TLV2474IPWPR remains stable with up to 100pF capacitive loads at unity gain, as verified by phase margin >61° in Figure 18 of the datasheet. For loads exceeding 10pF, TI recommends adding a 20Ω series null resistor (RNULL) between the output and load - a proven method to maintain stability without degrading DC accuracy or bandwidth.
Is TLV2474IPWPR pin-compatible with other TSSOP-14 quad op-amps like LM324PW?
No, TLV2474IPWPR is not pin-compatible with LM324PW or other legacy quad op-amps. Its TSSOP-14 pinout (1OUT, 1IN−, 1IN+, VDD, 2IN+, 2IN−, 2OUT, GND, 3OUT, 3IN−, 3IN+, 4IN+, 4IN−, 4OUT) follows a unique channel-interleaved arrangement optimized for low crosstalk - differing fundamentally from LM324PW's sequential channel layout.
Can TLV2474IPWPR operate from a single 2.7V supply?
Yes, TLV2474IPWPR is fully specified for 2.7V single-supply operation - including rail-to-rail input (0V to 2.7V common-mode range) and output swing within 180mV of both rails under 10mA load. All key parameters (GBW, VIO, IDD) are characterized at 2.7V in the Electrical Characteristics tables of SLOS232E.
What is the thermal performance of TLV2474IPWPR in TSSOP-14 package?
In TSSOP-14 (PWP) package, TLV2474IPWPR has θJA = 30.7°C/W and θJC = 2.07°C/W (per datasheet Dissipation Rating Table). At 2.4mA total supply current and 3.3V supply, power dissipation is ~7.9mW - resulting in <0.25°C junction-to-ambient rise, ensuring stable operation without heatsinking in standard PCB layouts.
