Product details
Overview
TLV2475AIPWR from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS operational amplifier with integrated shutdown control, 2.8-MHz gain-bandwidth product, 600 µA per channel supply current, and ±35 mA high-output drive capability at 5 V. It operates from 2.7 V to 6 V and is used in low-voltage sensor signal conditioning and portable medical instrumentation.
For engineers reviewing the TLV2475AIPWR datasheet, TLV2475AIPWR pinout, TLV2475AIPWR application, or TLV2475AIPWR equivalent, this page delivers verified electrical specs, TSSOP-16 package details, rail-to-rail I/O behavior, shutdown timing characteristics, and real-world design trade-offs versus comparable TI op-amps.
Technical Context
The TLV2475AIPWR implements a CMOS input stage enabling 2.5 pA typical input bias current and rail-to-rail common-mode input range (–0.2 V to VDD + 0.2 V). Its output stage delivers ±35 mA into loads while maintaining rail-to-rail swing under 500 mV of either supply rail at full load.
Shutdown functionality is controlled by logic-level inputs (V(ON) = 1.38 V, V(OFF) = 1.3 V at 5 V), reducing supply current to 1000 nA/channel. The device achieves 2.8 MHz GBW with 1.5 V/µs slew rate and maintains stability with capacitive loads up to 1000 pF when using recommended nulling resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-supply operation in battery-powered systems down to two alkaline cells. |
| Gain-Bandwidth Product | 2.8 MHz - enables stable unity-gain buffer or closed-loop amplification up to ~200 kHz at AV = 10. |
| Input Bias Current | 2.5 pA (typ) - minimizes voltage error in high-impedance sensor interfaces like pH electrodes or photodiode transimpedance stages. |
| Output Drive Capability | ±35 mA at 500 mV from rail - drives 600 Ω loads directly without external buffers in data acquisition front-ends. |
| Shutdown Supply Current | 1000 nA/channel at 5 V - extends battery life in intermittent-sampling applications such as wearable ECG monitors. |
| Input Offset Voltage | 250 µV (typ), 2000 µV (max over temp) - suitable for precision DC-coupled amplification where offset drift must stay below 0.5 mV. |
| Common-Mode Input Range | –0.2 V to VDD + 0.2 V - accepts signals beyond rails, simplifying level-shifting in mixed-supply systems. |
Pinout & Package
TSSOP-16 package with 0.65 mm pitch, 5.0 mm × 4.4 mm body, and exposed thermal pad (not electrically connected). RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | OUTx | Amplifier output terminals - each capable of sourcing/sinking ±35 mA while staying within 500 mV of supply rails. |
| 2, 5, 10, 13 | IN–x | Inverting inputs - high-impedance CMOS nodes (10¹² Ω) with 2.5 pA bias current for minimal loading. |
| 3, 6, 11, 14 | IN+x | Non-inverting inputs - rail-to-rail common-mode range supports direct connection to unbuffered sensors. |
| 7, 15 | GND | Analog ground reference - dual GND pins reduce ground bounce in multi-channel switching applications. |
| 8, 16 | VDD+ | Positive supply - accepts 2.7–6 V; internal regulation ensures consistent performance across voltage range. |
| 1/2SHDN, 3/4SHDN | Shutdown enable | Logic-controlled disable for channels 1&2 (pin 1/2SHDN) and 3&4 (pin 3/4SHDN); outputs go high-Z during shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3 V or lower systems - e.g., 0–3.3 V ADC input scaling without level shifters. |
| 600 µA/channel quiescent current | Supports always-on monitoring circuits with <2.4 mA total IQ for all four channels - critical for multi-sensor IoT edge nodes. |
| Independent dual shutdown controls | Allows selective channel disabling (e.g., keep channel 1 active for wake-up detection while shutting down channels 2–4 for sleep mode). |
| 2.8-MHz bandwidth with 1.5 V/µs slew rate | Accurately reproduces 100-kHz sine waves with <0.1% THD+N at AV = 10 - sufficient for anti-aliasing and reconstruction filters. |
| Stable with 1000-pF capacitive loads | Eliminates need for isolation resistors when driving ADC input capacitors or long PCB traces in industrial PLC analog modules. |
Applications
| Portable ECG Front-End | Multi-Channel Sensor Hub |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474IPW | No shutdown function; identical pinout and AC specs (2.8 MHz GBW, 600 µA/ch), but lacks SHDN pins. | Used where continuous operation is required and power cycling is handled externally. | Select TLV2474IPW when shutdown is unnecessary and cost reduction is prioritized. |
| OPA2333PWR | Zero-drift architecture (0.02 µV/°C drift), lower offset (2 µV typ), but higher IQ (17 µA/ch) and no shutdown. | Suitable for ultra-precision DC measurements where offset drift dominates error budget. | Choose OPA2333PWR only when sub-µV offset stability outweighs 28× higher supply current and absence of shutdown. |
Compared with TLV2474IPW, TLV2475AIPWR adds independent dual shutdown with 1000 nA/channel off-state current but same footprint and bandwidth; versus OPA2333PWR, it trades zero-drift precision for micropower operation and integrated power control - making it optimal for battery-constrained multi-channel systems requiring flexible power gating.

FAQ
What is the operating temperature range for TLV2475AIPWR?
The TLV2475AIPWR is rated for operation from –40°C to +125°C, meeting industrial and automotive ambient requirements. This range is confirmed in the "recommended operating conditions" table of the SLOS232A datasheet, and the 'I' suffix in the part number explicitly denotes the extended temperature grade.
Does TLV2475AIPWR support true rail-to-rail output swing under load?
Yes - TLV2475AIPWR delivers rail-to-rail output swing with ≤180 mV saturation voltage at ±10 mA load (3 V supply) and ≤500 mV at ±35 mA (5 V supply), as specified in the "High Output Drive Capability" section. This enables full-scale signal utilization in 3.3 V systems without external level-shifting circuitry.
How does the shutdown feature work on TLV2475AIPWR?
TLV2475AIPWR has two independent shutdown pins: pin 1/2SHDN controls channels 1 and 2; pin 3/4SHDN controls channels 3 and 4. Driving either pin below 1.3 V (at 5 V supply) places the corresponding amplifier outputs in high-impedance state and reduces supply current to 1000 nA/channel, as verified in the V(OFF) and IDD(SHDN) specifications.
Can TLV2475AIPWR drive a 600-Ω load at 2.8 MHz?
No - while TLV2475AIPWR has a 2.8-MHz gain-bandwidth product, its output drive is limited to ±35 mA at 500 mV from rail. Driving a 600-Ω load at full swing (e.g., ±3 V) requires ±5 mA, which is well within spec, but small-signal bandwidth into 600 Ω remains near 2.8 MHz; large-signal settling is constrained by slew rate (1.5 V/µs), limiting usable full-power bandwidth to ~235 kHz.
Is TLV2475AIPWR pin-compatible with other devices in the TLV247x family?
TLV2475AIPWR uses the TSSOP-16 package and shares pin assignments with TLV2474 in non-shutdown configurations (pins 1–16 map identically for IN+, IN–, OUT, GND, VDD+), but TLV2475AIPWR repurposes pins 1 and 16 as 1/2SHDN and 3/4SHDN. Therefore, it is not drop-in compatible with TLV2474IPW unless the PCB provides pull-up/down provisions for shutdown control.
