Product details
Overview
TLV2475IPWPR 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 capability at 500mV from rails. It operates from 2.7V to 6V and is designed for low-voltage sensor signal conditioning in battery-powered medical devices.
For engineers reviewing the TLV2475IPWPR datasheet, TLV2475IPWPR pinout, TLV2475IPWPR application, or TLV2475IPWPR equivalent, key selection criteria include rail-to-rail I/O swing, ultra-low shutdown current (1000nA/ch at 5V), input bias current (2.5pA), and TSSOP-16 packaging for high-density analog front-ends.
Technical Context
The TLV2475IPWPR implements a CMOS input stage enabling 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD). Its output stage delivers ±35mA into loads while maintaining 180mV rail clearance under 10mA load, supporting high-drive requirements without external buffers.
Integrated shutdown control places outputs in high-impedance state and reduces supply current to 1000nA per channel at 5V. The device is fully specified across –40°C to +125°C and supports stable operation with capacitive loads ≥10pF when using series nulling resistors (RNULL ≥20Ω).

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474IPWP | No shutdown pins - all four channels always active; identical GBW, drive, and bias specs | Suitable where continuous operation is required and power gating is unnecessary | Select TLV2474IPWP if system design does not require per-channel shutdown control |
| OPA2333PWR | Zero-drift architecture; 0.02μV/°C offset drift vs TLV2475IPWPR's 0.4μV/°C; higher 350μA/channel supply current | Better for DC-critical applications like precision weight scales; less suitable for high-speed pulse amplification | Select OPA2333PWR only when sub-μV offset stability over temperature is mandatory |
Compared with TLV2474IPWP, TLV2475IPWPR adds independent shutdown for channels 3–4 at no cost to AC performance or drive strength; versus OPA2333PWR, it trades zero-drift precision for lower quiescent current and higher output current - making it optimal for portable, high-drive, moderate-precision analog front-ends.

FAQ
What is the maximum capacitive load the TLV2475IPWPR can drive without oscillation?
The TLV2475IPWPR remains stable with capacitive loads up to 10pF when directly connected. For loads exceeding 10pF, a series nulling resistor (RNULL ≥20Ω) must be placed between the output and load capacitance to maintain phase margin above 61°. This requirement is documented in Figure 42 of the TLV2475IPWPR datasheet and verified across –40°C to +125°C.
Does the TLV2475IPWPR support true single-supply operation from 2.7V?
Yes, the TLV2475IPWPR supports true single-supply operation from 2.7V to 6V. Its rail-to-rail input common-mode range spans 0V to VDD, and its output swings to within 180mV of both rails under 10mA load. At 2.7V supply, this provides usable output swing from 0.18V to 2.52V - sufficient for driving 12-bit SAR ADCs with 2.5V reference.
How does the shutdown function work on the TLV2475IPWPR?
The TLV2475IPWPR features two dedicated shutdown pins (pins 15 and 16) controlling channels 3 and 4 independently. Applying ≤0.8V to either pin places the corresponding amplifier's output in high-impedance state and reduces its supply current to 1000nA at 5V. Channels 1 and 2 lack shutdown control and remain active at all times. Logic thresholds are specified at VIL = 0.8V and VIH = 2.0V.
What is the typical input offset voltage drift over temperature for TLV2475IPWPR?
The TLV2475IPWPR has a typical input offset voltage drift (αVIO) of 0.4μV/°C. Over the full operating range of –40°C to +125°C, this results in a maximum drift contribution of 66μV (165°C × 0.4μV/°C), added to the initial 250μV typical offset. This drift performance is confirmed in the Electrical Characteristics table on page 4 of the TLV2475IPWPR datasheet.
Can TLV2475IPWPR replace TLV2474IPWP in an existing PCB layout?
No - TLV2475IPWPR cannot be used as a drop-in replacement for TLV2474IPWP. Although both use TSSOP-16 packages, pin functions differ: TLV2475IPWPR uses pins 15–16 for 3/4SHDN, whereas TLV2474IPWP assigns those pins to NC (no internal connection). Using TLV2475IPWPR in a TLV2474IPWP layout would cause unintended shutdown of channels 3–4 unless the SHDN pins are tied to VDD.
