Product details
Overview
TLV2474CPWPR 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, ±35mA output drive at 500mV from rails, 600μA/channel supply current, and 250μV typical input offset voltage across 2.7V–6V operation - ideal for portable medical sensor front-ends and battery-powered data acquisition.
For engineers reviewing the TLV2474CPWPR datasheet, TLV2474CPWPR pinout, TLV2474CPWPR application, or TLV2474CPWPR equivalent, key selection criteria include its shutdown-capable TSSOP-14 package, rail-to-rail I/O swing enabling full dynamic range at 3V, ultra-low 350nA/channel shutdown current at 3V, and verified performance across –40°C to +125°C industrial temperature range.
Technical Context
The TLV2474CPWPR 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 load). Its architecture supports stable unity-gain operation with ≥61° phase margin into 1000pF capacitive loads when configured with appropriate feedback networks.
It features independent channel shutdown control via dedicated SHDN pins (pins 3/4), placing outputs in high-impedance state while reducing per-channel supply current to 350nA at 3V. The device is fully specified at both 3V and 5V supplies and maintains consistent ac performance across the extended industrial temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474IPWP | Same electrical specs but rated for –40°C to +125°C industrial temp range; no C-suffix screening | Required for automotive under-hood or industrial motor control ambient conditions | Select TLV2474IPWP when operating beyond 70°C ambient or requiring extended temperature qualification |
| OPA2340UA/2K5 | Lower 500μA/channel supply current but only 1MHz GBW; no shutdown function; SO-8 dual-only packaging | Lacks quad configuration and shutdown, limiting use in space-constrained multi-channel systems | Choose OPA2340 for ultra-low-power dual-channel designs where 1MHz bandwidth suffices and shutdown is unnecessary |
Compared with TLV2474IPWP, TLV2474CPWPR offers tighter initial offset and lower cost for commercial-temperature applications; versus OPA2340UA/2K5, it provides higher bandwidth, quad integration, and shutdown - critical for scalable sensor arrays and battery longevity.

FAQ
What is the maximum capacitive load the TLV2474CPWPR can drive without instability?
The TLV2474CPWPR maintains ≥61° phase margin into 1000pF loads when configured with 10kΩ feedback and gain ≥2. For loads >10pF, TI recommends adding a 20Ω series null resistor between output and capacitive node to preserve stability - a requirement confirmed in Figure 42 of the SLOS232E datasheet. This enables direct interface with ADC input filters without oscillation risk.
Does the TLV2474CPWPR support true rail-to-rail input common-mode range?
Yes, the TLV2474CPWPR supports a true rail-to-rail input common-mode voltage range from 0V to VDD across its full operating supply (2.7V–6V) and temperature range (0°C to +70°C). This is explicitly specified in the Recommended Operating Conditions table and verified in Figure 1 and Figure 2 of the datasheet, enabling direct sensing of signals referenced to ground or VDD in single-supply configurations.
How does shutdown functionality work on the TLV2474CPWPR?
The TLV2474CPWPR uses two dedicated active-high shutdown pins: pin 3 (SHDN1) controls channels 1 and 2, while pin 4 (SHDN2) controls channels 3 and 4. Driving either pin below 0.8V disables the corresponding pair, placing outputs in high-impedance state and reducing per-channel supply current to 350nA at 3V. Turn-on/off times are 5μs and 250ns respectively, as measured in Figure 33 and Figure 34.
What is the output voltage swing specification for TLV2474CPWPR at 10mA load?
At 10mA load and 3V supply, the TLV2474CPWPR delivers an output voltage swing of 0.2V to 2.8V - i.e., within 200mV of each rail. At 5V supply, it achieves 0.35V to 4.65V swing under identical conditions. These values are specified in the Electrical Characteristics tables (pages 4–5) for VOL and VOH parameters at IOL = 10mA and IOH = –10mA test conditions.
Is TLV2474CPWPR pin-compatible with other packages in the TLV247x family?
No, TLV2474CPWPR (TSSOP-14) is not pin-compatible with TLV2474CD (SOIC-14) or TLV2474CN (PDIP-14), despite identical channel count and functionality. Pin assignments differ: TSSOP-14 places GND at pin 8 and uses pins 3/4 for SHDN, whereas SOIC-14 assigns GND to pin 7 and lacks dedicated SHDN pins. Always verify pinout using the "TLV2474 D, N, OR PWP PACKAGE" diagram on page 2 of SLOS232E.
