Product details
Overview
TLV2475CDR 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-ideal for low-voltage sensor signal conditioning in portable medical devices and battery-powered data acquisition systems.
For engineers reviewing the TLV2475CDR datasheet, TLV2475CDR pinout, TLV2475CDR application, or TLV2475CDR equivalent, key selection considerations include its 16-pin TSSOP package with dual shutdown control (pins 3/4SHDN), ultra-low 350nA/channel shutdown current at 3V, rail-to-rail swing capability down to 180mV of supply rails, and guaranteed operation across –40°C to +125°C industrial temperature range.
Technical Context
The TLV2475CDR employs a CMOS input stage enabling 2.5pA typical input bias current and rail-to-rail common-mode input voltage range (0 V to VDD). Its output stage supports true rail-to-rail swing under load: ±10mA within 180mV of rails and ±35mA within 500mV-addressing a key limitation of legacy micropower op-amps.
Integrated shutdown logic activates when SHDN pins are pulled low (<0.8V), placing all four amplifiers into high-impedance output state while reducing per-channel supply current to 350nA at 3V or 1000nA at 5V. The device is fully specified at both 3V and 5V single-supply operation across the extended industrial temperature range.
Key Specifications

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 |
|---|---|---|---|
| TLV2474CDR | No shutdown function; identical pinout and electrical specs except missing SHDN pins | Suitable where continuous operation is required and power gating is handled externally | Select when system-level power management already exists and quad channel count is mandatory |
| OPA4340UA | Higher 1.2mA/channel supply current; 5.5MHz GBW; no shutdown; SO-14 package | Better AC performance but 2× higher quiescent power; incompatible pinout and footprint | Choose when bandwidth >2.8MHz is critical and PCB redesign is acceptable |
Compared with TLV2474CDR, the TLV2475CDR adds independent channel-pair shutdown control without sacrificing rail-to-rail performance or package compatibility; versus OPA4340UA, it trades bandwidth for 50% lower supply current and integrated power gating-making TLV2475CDR optimal for battery longevity and thermal-constrained designs.

FAQ
What is the maximum supply voltage rating for TLV2475CDR?
The absolute maximum supply voltage for TLV2475CDR is 7V. Operation above this level 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 voids specification compliance even if below 7V.
Does TLV2475CDR support true rail-to-rail output swing under load?
Yes, TLV2475CDR delivers rail-to-rail output swing under defined load conditions: ±10mA within 180mV of each rail and ±35mA within 500mV. This is verified across temperature and supply voltage (3V and 5V) and enables direct interfacing with 12-bit ADCs and low-dropout voltage references without level-shifting circuitry.
How does the shutdown function operate on TLV2475CDR?
TLV2475CDR features two independent shutdown pins: 1/2SHDN (pin 15) and 3/4SHDN (pin 16). Driving either pin below 0.8V (VIL) disables its associated amplifier pair, placing outputs in high-impedance state and reducing per-channel supply current to 350nA at 3V. Both pins must be high (>2V, VIH) for full quad operation.
What is the input offset voltage specification for TLV2475CDR over temperature?
TLV2475CDR has a typical input offset voltage of 250μV at +25°C, with a maximum of 2400μV over the full –40°C to +125°C industrial temperature range. Its temperature coefficient is 0.4μV/°C, meaning offset drift contributes less than 50μV over a 125°C span-critical for precision DC-coupled sensor interfaces.
Is TLV2475CDR compatible with standard TSSOP-16 PCB footprints?
Yes, TLV2475CDR uses the industry-standard TSSOP-16 (PWP) package with 0.65mm pitch and 5.0mm × 4.4mm body dimensions. It is mechanically and solder-reflow compatible with JEDEC MO-153 specifications, supporting automated assembly and IPC Class 2/3 reliability requirements without footprint modification.
