Product details
Overview
TLV2475IDR from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality, 2.8MHz gain-bandwidth product, 600μA per channel supply current, and ±35mA output drive at 500mV from rail-designed for low-voltage sensor signal conditioning in portable medical devices and battery-powered data acquisition systems.
For engineers reviewing the TLV2475IDR datasheet, TLV2475IDR pinout, TLV2475IDR application, or TLV2475IDR equivalent, this page delivers verified electrical parameters, TSSOP-16 package mapping, shutdown timing behavior, rail-to-rail dynamic range implications, and real-world alternative selection guidance for precision analog front-ends.
Technical Context
The TLV2475IDR implements a CMOS input stage enabling 2.5pA typical input bias current and rail-to-rail common-mode input range (0 V to VDD). Its output stage supports true rail-to-rail swing under load: ±10mA within 180mV of each rail and ±35mA at 500mV off-rail, making it suitable for single-supply 2.7V–6V systems where headroom is constrained.
Shutdown mode reduces supply current to 1000nA per channel at 5V (350nA at 3V), with turn-on/turn-off times of 5μs and 250ns respectively. The device maintains stable operation with ≥61° phase margin into 1000pF capacitive loads and exhibits 2.8MHz unity-gain bandwidth across its full operating temperature range (–40°C to +125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.8MHz - enables stable closed-loop operation up to ~200kHz with moderate noise gain in sensor amplification stages. |
| Supply current per channel | 600μA - allows four independent amplifiers to operate continuously on <3mA total supply current in ultra-low-power systems. |
| Input bias current | 2.5pA - minimizes voltage error across high-impedance sensor sources (e.g., pH electrodes, piezoresistive bridges). |
| Output drive capability | ±35mA at 500mV from rail - directly drives ADC reference buffers, LED drivers, or low-impedance transducers without external boost stages. |
| Rail-to-rail I/O | Full swing from 0V to VDD on both inputs and outputs - maximizes usable dynamic range in 3V or 3.3V single-supply applications. |
| Shutdown current per channel | 1000nA at 5V - reduces quiescent power by >99.8% during idle periods in duty-cycled measurement systems. |
| Input offset voltage | 250μV (typ) - limits DC error to <0.5mV in 2V full-scale instrumentation amplifier configurations. |
Pinout & Package

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 |
|---|---|---|---|
| TLV2474IDR | No shutdown pins - fixed four-channel operation; otherwise identical AC/DC specs and pinout. | Suitable only where continuous operation is required; cannot support duty-cycled power management. | Select TLV2474IDR if shutdown functionality is unnecessary and board layout must retain identical footprint. |
| OPA2333PWR | Zero-drift architecture (0.02μV/°C offset drift); higher 350kHz GBW but lower 16mA output drive; no shutdown. | Better for DC-critical applications like precision weigh scales; insufficient drive for low-Z loads. | Choose OPA2333PWR when long-term DC stability outweighs output drive and power cycling needs. |
Compared with TLV2474IDR, the TLV2475IDR adds dual independent shutdown controls without sacrificing bandwidth or precision-making it superior for energy-constrained systems. Versus OPA2333PWR, TLV2475IDR trades zero-drift performance for higher output current and integrated power gating, better matching portable sensor interface requirements.

FAQ
What is the maximum supply voltage rating for TLV2475IDR?
The absolute maximum supply voltage for TLV2475IDR is 7V. Operation beyond this limit risks permanent damage. The recommended operating range is 2.7V to 6V, with full electrical specifications guaranteed across that span at temperatures from –40°C to +125°C. Exceeding 6V may cause parametric degradation even if below the 7V absolute maximum.
Does TLV2475IDR support true rail-to-rail output swing under load?
Yes, TLV2475IDR delivers rail-to-rail output swing under specified load conditions: it swings to within 180mV of each rail while sourcing or sinking ±10mA, and to within 500mV while delivering ±35mA. This behavior is characterized and guaranteed across temperature and supply voltage-enabling full dynamic range utilization in single-supply 3V and 3.3V systems.
How does the shutdown function work on TLV2475IDR?
TLV2475IDR features two independent shutdown pins: 1/2SHDN controls channels 1 and 2, while 3/4SHDN controls channels 3 and 4. Driving either pin below 0.8V (VIL) places the associated channels in ultra-low-power state (1000nA/channel at 5V), disabling output stages and placing outputs in high-impedance state. Turn-on time is 5μs; turn-off time is 250ns.
What is the input offset voltage specification for TLV2475IDR over temperature?
TLV2475IDR has a typical input offset voltage of 250μV at +25°C, with a maximum of 2000μV over the full –40°C to +125°C operating range. Its offset voltage temperature coefficient is 0.4μV/°C, meaning drift contributes less than 60μV over a 150°C span-making it suitable for applications requiring moderate DC precision without auto-zeroing.
Which package type is used by TLV2475IDR and what are its key mechanical features?
TLV2475IDR uses the TSSOP-16 (PWP) package: 5.0mm × 4.4mm body size, 0.65mm lead pitch, 16-pin surface-mount outline with gull-wing leads. It includes an exposed thermal pad (non-electrical) for improved heat dissipation. Pin 1 is identified by a beveled edge or molded dot, and the device is rated for reflow soldering per JEDEC J-STD-020.
