Product details
Overview
TLV2475IPWR from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS operational amplifier with integrated shutdown control, 2.8-MHz gain-bandwidth product, 600 µA per channel supply current, and ±35 mA high-output drive capability at 500 mV from rails-designed for low-voltage sensor signal conditioning in portable medical devices.
For engineers reviewing the TLV2475IPWR datasheet, TLV2475IPWR pinout, TLV2475IPWR application, or TLV2475IPWR equivalent, this page delivers verified electrical specs, TSSOP-16 package layout, shutdown timing behavior, rail-to-rail dynamic range implications, and direct alternatives for battery-powered analog front-ends.
Technical Context
The TLV2475IPWR implements a CMOS input stage with 2.5 pA typical input bias current and rail-to-rail output swing capable of sourcing/sinking ±35 mA within 500 mV of either supply rail at 5 V. Its 2.8-MHz unity-gain bandwidth and 1.5 V/µs slew rate support medium-speed signal buffering and active filtering.
Shutdown functionality is implemented via dedicated SHDN pins (pins 1/2SHDN and 3/4SHDN), enabling independent channel disable with 350 nA/channel (3 V) or 1000 nA/channel (5 V) quiescent current. Input offset voltage is 250 µV (typ) with 0.4 µV/°C drift, supporting precision DC-coupled amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad op-amp with four independent amplifiers and two shared shutdown controls (1/2 and 3/4) |
| Supply Voltage Range | 2.7 V to 6 V single-supply operation-enables direct interface with Li-ion, 3.3 V, and 5 V systems |
| Gain-Bandwidth Product | 2.8 MHz-supports stable closed-loop gain ≥10 up to ~280 kHz with 10-kΩ load |
| Output Drive | ±35 mA at 500 mV from rail-drives low-impedance loads (e.g., 150 Ω DAC buffers, ADC drivers) without external boost |
| Shutdown Current | 1000 nA/channel at 5 V-reduces total system standby power to <4 µA for all four channels |
| Input Offset Voltage | 250 µV (typ) at 25°C-minimizes DC error in precision instrumentation and sensor gain stages |
| Common-Mode Range | Rail-to-rail input (–0.2 V to VDD + 0.2 V) and output (within 180 mV of rails at 10 mA)-maximizes dynamic range in 3 V systems |
Pinout & Package
TSSOP-16 package (PW suffix), 5.0 mm × 4.4 mm body, 0.65 mm pitch, exposed pad optional for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 | 1/2SHDN, 3/4SHDN | Dual shutdown inputs: logic-low disables channels 1&2 (pin 1) or 3&4 (pin 13); high-impedance CMOS input |
| 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15, 16 | Amplifier I/O and supplies | Pins 2–5: CH1 (OUT, IN–, IN+, GND); 6–9: CH2 (OUT, IN–, IN+, VDD+); 10–12: CH3 (OUT, IN–, IN+); 14–16: CH4 (OUT, IN–, IN+) |
| GND (Pin 5) | Analog ground reference | Single ground pin shared by all four amplifiers-requires low-impedance PCB connection to minimize crosstalk |
| VDD+ (Pin 9) | Positive supply | Single VDD pin powers all four amplifiers-decoupling capacitor (0.1 µF) required adjacent to pin 9 |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal swing in 3 V systems-no headroom loss at input or output stage |
| 600 µA per channel supply current | Supports always-on sensor interfaces with <2.4 mA total quiescent current across four channels |
| Independent dual shutdown control | Allows selective channel disabling-e.g., keep CH1/CH2 active for continuous monitoring while powering down CH3/CH4 during idle |
| ±35 mA output drive at 500 mV from rail | Eliminates need for external output buffers when driving 10-bit SAR ADC references or LED bias circuits |
| 2.5 pA input bias current | Preserves accuracy in high-impedance pH, thermopile, or photodiode transimpedance applications |

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 |
|---|---|---|---|
| TLV2474IPW | No shutdown function; identical pinout, GBW, drive, and supply current | Suitable where all four channels operate continuously-eliminates SHDN routing complexity | Select TLV2474IPW if shutdown is unnecessary and board layout simplicity is prioritized |
| OPA4340UA | Higher precision (125 µV max VIO), lower noise (12 nV/√Hz), but 750 µA/channel and no shutdown | Better for high-resolution data acquisition where offset and noise dominate; not suitable for ultra-low-power sleep modes | Choose OPA4340UA when DC accuracy and AC noise performance outweigh shutdown capability and quiescent current |
Compared with TLV2475IPWR, TLV2474IPW removes shutdown control while retaining identical performance and footprint-ideal for always-on designs-whereas OPA4340UA trades 25% higher supply current and no shutdown for superior DC precision and noise, targeting resolution-critical rather than power-constrained applications.

FAQ
What is the operating temperature range for TLV2475IPWR?
The TLV2475IPWR is rated for operation from –40°C to +125°C, meeting industrial and extended-temperature requirements. This range is confirmed in the "recommended operating conditions" table of the SLOS232A datasheet, and applies to the I-suffix variant denoted by the 'I' in TLV2475IPWR. The device maintains specified performance-including 2.8-MHz gain-bandwidth and 600 µA/channel supply current-across this full range.
Does TLV2475IPWR support true rail-to-rail output swing under load?
Yes, TLV2475IPWR delivers rail-to-rail output swing: it can drive ±10 mA while staying within 180 mV of each supply rail, and ±35 mA within 500 mV of the rails at 5 V. These values are measured and guaranteed in the "electrical characteristics" tables for both 3 V and 5 V operation. The output stage uses complementary CMOS architecture, enabling symmetric sourcing and sinking near the supply limits.
How does the shutdown feature work on TLV2475IPWR?
TLV2475IPWR has two independent shutdown inputs: pin 1 (1/2SHDN) disables channels 1 and 2, and pin 13 (3/4SHDN) disables channels 3 and 4. Driving either pin below 0.81 V (typ) at 25°C places the associated amplifiers in high-impedance output state and reduces their supply current to 1000 nA/channel at 5 V. Turnoff time is 250 ns, and turnon time is 5 µs-verified in the "operating characteristics" section of the datasheet.
What is the input offset voltage specification for TLV2475IPWR?
The TLV2475IPWR has a typical input offset voltage of 250 µV at 25°C, with a maximum of 2400 µV across the full –40°C to 125°C temperature range. For the A-grade variant (TLV2475A), the max is reduced to 2000 µV. This parameter is explicitly listed in the "electrical characteristics" tables for both 3 V and 5 V supply conditions, and its temperature coefficient is 0.4 µV/°C-critical for precision DC-coupled applications.
Which package type does TLV2475IPWR use, and what are its key mechanical features?
TLV2475IPWR uses the TSSOP-16 (PW) package: 5.0 mm × 4.4 mm body size, 0.65 mm lead pitch, and 1.2 mm maximum height. It is a surface-mount, leaded plastic package with gull-wing leads, qualified for reflow soldering per JEDEC J-STD-020. The 'PWR' suffix confirms tape-and-reel packaging (1000 units per reel), and the 'I' temperature grade indicates –40°C to 125°C operation-fully documented in TI's "available options" tables.
