Product details
Overview
TLV2475AIPWP from Texas Instruments is a quad-channel rail-to-rail input/output operational amplifier with shutdown functionality, delivering 2.8MHz gain-bandwidth, 600μA/channel supply current, ±35mA output drive at 500mV from rails, and 250μV typical input offset voltage. It operates from 2.7V to 6V and targets low-voltage sensor signal conditioning in portable medical devices and battery-powered data acquisition systems.
For engineers reviewing the TLV2475AIPWP datasheet, TLV2475AIPWP pinout, TLV2475AIPWP application, or TLV2475AIPWP equivalent, this page provides verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options for precision analog front-end design under tight power and dynamic range constraints.
Technical Context
The TLV2475AIPWP uses CMOS input stage architecture enabling rail-to-rail common-mode input range (0V to VDD) and rail-to-rail output swing-critical for maximizing signal fidelity in single-supply 3V/5V systems. Its 2.8MHz unity-gain bandwidth supports moderate-speed signal amplification without sacrificing micropower efficiency.
Each channel integrates independent shutdown control (active-low), reducing quiescent current to 1000nA/channel at 5V during sleep mode while placing outputs in high-impedance state. The device is fully specified across –40°C to +125°C and features 10¹²Ω differential input resistance and 92dB CMRR at 25°C.
Key Specifications

|---|---|
| Gain-bandwidth product | 2.8MHz - enables stable closed-loop operation up to ~200kHz with gain ≥10. |
| Supply current per channel | 600μA at 5V - allows four op-amps to operate within 2.4mA total, ideal for ultra-low-power systems. |
| Output drive capability | ±35mA at 500mV from rail - supports direct driving of ADC reference buffers or low-impedance transducers. |
| Rail-to-rail I/O | Input common-mode range: 0V to VDD; Output swing: within 180mV of rails at 10mA - maximizes dynamic range in 3V systems. |
| Input offset voltage | 250μV (typ) - ensures <0.5% error in 500mV full-scale sensor interfaces without trimming. |
| Shutdown current | 1000nA/channel at 5V - reduces system standby power by >99.9% versus active mode. |
| Supply voltage range | 2.7V to 6V - compatible with Li-ion, 3.3V logic, and dual-supply derived rails. |

| 9 | Channel 3 output | Third independent output; layout symmetry recommended to match thermal behavior with Pins 1 and 7. |
| 10 | Channel 3 inverting input | Same input structure as Pins 2 and 6; verify layout symmetry for multi-channel matching. |
| 11 | Channel 3 non-inverting input | Provides third signal path; guard ring recommended when used with high-Z sources. |
| 12 | GND | Second ground connection; ties to same analog ground plane as Pin 4-no split planes. |
| 13 | Channel 4 non-inverting input | Final input terminal; ensure equal trace length to Pin 14 for common-mode rejection in differential pairs. |
| 14 | Channel 4 inverting input | Paired with Pin 13 for fourth channel; matches input capacitance (18.9pF) and bias current. |
| 15 | Channel 4 output | Fourth rail-to-rail output; supports simultaneous 4-channel signal conditioning in compact space. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474IPWP | No shutdown pin; identical GBW, drive, and offset specs; same TSSOP-16 package. | Used where continuous operation is required and power cycling is handled externally. | Select when system-level power management eliminates need for per-op-amp shutdown control. |
| OPA2333AIPW | Zero-drift architecture; 2μV max VIO; 17μA/channel supply current; no shutdown; SOIC-16 package. | Preferred for high-accuracy DC-coupled applications requiring <1μV/°C drift, but consumes 28× more current. | Choose only when offset drift dominates error budget and power is secondary to precision. |
Compared with TLV2475AIPWP, TLV2474IPWP removes shutdown functionality while retaining identical analog performance and footprint-ideal for cost-sensitive always-on designs. OPA2333AIPW trades 28× higher quiescent current for 100× lower offset drift, making it suitable only for ultra-stable DC measurements where battery life is not constrained.

FAQ
What is the maximum output current capability of the TLV2475AIPWP at 3V supply?
The TLV2475AIPWP delivers ±35mA output current when the output is within 500mV of either supply rail at 5V operation. At 3V supply, the datasheet specifies ±10mA at 180mV from rail and ±35mA at 500mV from rail-confirming the same ±35mA capability remains valid at 3V, provided headroom constraints are met. This is confirmed in the "High Output Drive Capability" section of the SLOS232E datasheet.
Does the TLV2475AIPWP support true rail-to-rail input common-mode range?
Yes, the TLV2475AIPWP supports rail-to-rail input common-mode voltage range from 0V to VDD across its full operating temperature range (–40°C to +125°C). This is explicitly stated in the "RECOMMENDED OPERATING CONDITIONS" table and verified in Figure 1 (input offset voltage vs. common-mode input voltage) of the SLOS232E datasheet, showing stable VIO across the entire 0–3V and 0–5V spans.
How does the shutdown function behave on the TLV2475AIPWP?
The TLV2475AIPWP features a single active-low shutdown pin (Pin 16) that globally disables all four amplifier channels. When SHDN is pulled low, outputs enter high-impedance state and supply current drops to 1000nA/channel at 5V (350nA/channel at 3V). Turn-off time is 250ns and turn-on time is 5μs, as measured under RL = OPEN conditions per the "OPERATING CHARACTERISTICS" table in SLOS232E.
What is the typical input bias current of the TLV2475AIPWP and why does it matter?
The TLV2475AIPWP has a typical input bias current of 2.5pA at 25°C, with a full-range maximum of 300pA (–40°C to +125°C). This ultra-low value minimizes voltage errors across high-impedance sensor sources (e.g., pH electrodes, photodiodes), preventing signal degradation in precision measurement paths where even 1MΩ source resistance would generate >2.5μV error with higher-bias op-amps.
Can the TLV2475AIPWP drive capacitive loads directly, and what is the recommended approach?
The TLV2475AIPWP becomes unstable with capacitive loads >10pF due to reduced phase margin. The datasheet recommends inserting a series null resistor (RNULL) between the output and load-minimum 20Ω-for loads exceeding 10pF. This is detailed in Figure 42 ("Driving a Capacitive Load") and confirmed by phase margin vs. load capacitance curves (Figures 18–19), which show stability recovery with RNULL ≥20Ω at CL = 100pF.
