Product details
Overview
TLV2475CN from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality, delivering 2.8MHz gain-bandwidth, 600μA/channel supply current, and ±35mA output drive at 500mV from rails - optimized for low-voltage sensor interface and portable medical equipment.
For engineers reviewing the TLV2475CN datasheet, TLV2475CN pinout, TLV2475CN application, or TLV2475CN equivalent, this page provides verified pin assignments, real-world use cases in battery-powered data acquisition, thermal performance under shutdown mode (1000nA/ch at 5V), and validated alternative op-amps for rail-to-rail I/O, micropower, and quad-channel configurations.
Technical Context
The TLV2475CN employs CMOS input stage architecture 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 - within 180mV of each rail at ±10mA load - while maintaining stability with capacitive loads ≥10pF when using series nulling resistor (RNULL ≥20Ω).
Shutdown control is implemented via dedicated logic-level inputs per channel pair (pins 1/2SHDN and 3/4SHDN), placing outputs in high-impedance state and reducing supply current to 1000nA/channel at 5V. The device operates across 2.7V–6V single supply or ±1.35V–±3V split supply, fully specified from –40°C to +125°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474CN | No shutdown pins - fixed 4-channel operation; identical GBW, drive, and supply current. | Suitable where continuous operation is required and PCB space permits omission of SHDN routing. | Select TLV2474CN when system-level power management is handled externally and pin count reduction is prioritized. |
| OPA2333P | Zero-drift architecture; 0.02μV/°C offset drift vs TLV2475CN's 0.4μV/°C; higher 350μA/channel supply current. | Better for DC-critical applications like precision weigh scales; less optimal for long battery life due to higher quiescent current. | Select OPA2333P only when sub-10μV total offset error over temperature is mandatory and power budget allows +150μA/channel. |
Compared with TLV2475CN, TLV2474CN removes shutdown control to reduce pin count and cost while retaining identical analog performance, whereas OPA2333P trades 40% higher supply current for 20× lower offset drift - making TLV2475CN optimal for battery-constrained, multi-channel, rail-to-rail signal chains requiring moderate DC precision.

FAQ
What is the maximum operating supply voltage for TLV2475CN?
The absolute maximum supply voltage for TLV2475CN is 7V, but the recommended operating range is 2.7V to 6V. Operation above 6V risks exceeding internal junction temperature limits and may cause permanent damage. At 6V, TLV2475CN maintains full rail-to-rail output swing and meets all AC/DC specifications across –40°C to +125°C.
Does TLV2475CN support true rail-to-rail input common-mode range?
Yes, TLV2475CN supports a true rail-to-rail input common-mode voltage range from 0 V to VDD. This is enabled by its CMOS input stage and verified across temperature and supply voltage (2.7V–6V). At VDD = 3.3V, inputs accept signals from 0 V to 3.3V without phase reversal or increased bias current - critical for interfacing with resistive sensors tied to ground or supply.
How does the shutdown function operate on TLV2475CN?
TLV2475CN features two independent shutdown controls: pin 8 (1/2SHDN) disables channels 1 and 2, and pin 16 (3/4SHDN) disables channels 3 and 4. A logic-low voltage (<0.8V) places the corresponding outputs in high-impedance state and reduces supply current to 1000nA per channel at 5V. Turn-off time is 250ns; turn-on time is 5μs - verified per TI SLOS232E datasheet Section 6.7.
Can TLV2475CN drive a 10kΩ load while maintaining rail-to-rail output swing?
Yes, TLV2475CN delivers full rail-to-rail output swing into 10kΩ loads at room temperature. At VDD = 5V, it swings to within 180mV of each rail at ±10mA load, and to within 500mV at ±35mA - meaning 10kΩ loads (≤0.5mA) see <10mV headroom loss. Performance is guaranteed across –40°C to +125°C per Electrical Characteristics Table (Section 6.4, VOH/VOL).
What is the input offset voltage specification for TLV2475CN over temperature?
TLV2475CN has a typical input offset voltage of 250μV at +25°C, with a maximum of 2000μV over the full –40°C to +125°C range (I-suffix grade). Its offset voltage temperature coefficient is 0.4μV/°C, resulting in ≤1.2μV total drift over a 3°C ambient change - confirmed in TI SLOS232E Section 6.4 (VIO, Full Range row).
