Product details
Overview
TLV2455ID from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for ultralow-power, low-voltage portable systems. It delivers 220 kHz gain-bandwidth, ±10 mA output drive, 23 µA/channel supply current, and operates from 2.7 V to 6 V - enabling high-precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2455ID datasheet, TLV2455ID pinout, TLV2455ID application, or TLV2455ID equivalent, this page provides verified electrical specs, shutdown timing behavior, rail-to-rail dynamic range implications, and validated alternative options for space-constrained, low-quiescent-current designs.
Technical Context
The TLV2455ID implements a CMOS input stage with rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 250 mV of rails at 2.5 mA load). Its internal architecture supports stable unity-gain operation with 56° phase margin into 1 nF capacitive loads.
It features independent per-amplifier shutdown control (pins 1/2SHDN and 3/4SHDN), reducing total quiescent current to 16 nA per channel during sleep mode while placing outputs in high-impedance state - critical for multiplexed sensor interfaces and power-gated analog subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion, 3.3 V, and 5 V systems without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - enables stable DC-coupled amplification up to ~20 kHz with gain ≥10. |
| Supply Current per Channel | 23 µA - allows >1-year battery life in always-on ECG front-ends powered by CR2032. |
| Input Offset Voltage | 20 µV (typ) - ensures <1 LSB error in 16-bit SAR ADC driver applications at unity gain. |
| Output Drive Capability | ±10 mA - drives 500 Ω loads directly, eliminating external buffers in transducer interfaces. |
| Shutdown Current per Channel | 16 nA - reduces system standby power by >99.9% versus active mode. |
| Common-Mode Rejection Ratio | 80 dB (typ) - suppresses noise in differential sensor bridges operating near ground or rail. |
Pinout & Package
TSSOP-16 package (PW suffix), 5.0 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, thermally enhanced pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT, 2OUT, 3OUT, 4OUT | Amplifier output terminals | Each drives rail-to-rail loads up to ±10 mA; high-Z during associated SHDN assertion. |
| 1IN−, 2IN−, 3IN−, 4IN− | Inverting inputs | CMOS inputs with 0.3–4.5 nA bias current; support 0 V to VDD common-mode range. |
| 1IN+, 2IN+, 3IN+, 4IN+ | Non-inverting inputs | Matched to inverting inputs; enable precision instrumentation and difference amplifiers. |
| GND | Analog ground reference | Single ground connection for all four amplifiers; requires low-impedance PCB return path. |
| VDD+ | Positive supply rail | Accepts 2.7–6 V; PSRR of 106 dB minimizes supply ripple coupling into signal path. |
| 1/2SHDN, 3/4SHDN | Independent shutdown controls | Active-high logic; asserts high-Z output and cuts IDD to 16 nA per enabled amplifier pair. |
Key Features

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 |
|---|---|---|---|
| TLV2475IDR | Higher 600 µA/channel supply current, 2.8 MHz GBW, 1.5 V/µs slew rate - trades power for speed. | Requires redesign of power budget and thermal layout; unsuitable for multi-year battery life targets. | Select when >100 kHz closed-loop bandwidth or fast settling (<5 µs) is required. |
| LPV821QDGKR | Lower 650 nA/channel supply current, 10 kHz GBW, no shutdown pins - optimized for nano-power, not performance. | Lacks independent shutdown and rail-to-rail output; cannot drive 500 Ω loads or meet 16-bit linearity. | Select only for ultra-long-life, low-bandwidth sensor monitoring where speed is secondary. |
Compared with TLV2455ID, TLV2475IDR offers 12× higher bandwidth but consumes 26× more current, making it viable only in AC-powered or short-duration portable use; LPV821QDGKR achieves 35× lower quiescent current but sacrifices 22× bandwidth and removes shutdown control - limiting its utility in dynamically powered systems.

FAQ
What is the operating temperature range for TLV2455ID?
The TLV2455ID is rated for operation from −40°C to +125°C, as indicated by the "I" suffix in the part number. This extended industrial temperature range is fully specified in the datasheet for parameters including input offset voltage, supply current, and CMRR - making TLV2455ID suitable for under-hood automotive sensors and industrial process controllers without derating.
Does TLV2455ID support true rail-to-rail input and output operation?
Yes, TLV2455ID supports rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 250 mV of each rail at 2.5 mA load). This capability is confirmed in the device description and electrical characteristics tables for both 3 V and 5 V supplies - enabling full utilization of ADC input ranges in low-voltage systems without external level-shifting circuitry.
How does the shutdown function work on TLV2455ID?
TLV2455ID features two independent shutdown pins: pin 1 (1/2SHDN) controls amplifiers 1 and 2, and pin 16 (3/4SHDN) controls amplifiers 3 and 4. When driven high (≥2 V at VDD = 5 V), each pair enters shutdown mode, reducing supply current to 16 nA per channel and placing outputs in high-impedance state - verified in the Electrical Characteristics table under IDD(SHDN) with SHDN = VDD.
What package type is used for TLV2455ID?
TLV2455ID is supplied in a TSSOP-16 package (PW suffix), measuring 5.0 mm × 4.4 mm × 1.2 mm with 0.65 mm lead pitch and an exposed thermal pad. This package is explicitly listed in the "TLV2454 and TLV2455 AVAILABLE OPTIONS" table for the "I" temperature grade and confirmed in the "TLV245x PACKAGE PINOUTS" diagram labeled "TLV2455 D, N, OR PW PACKAGE".
Can TLV2455ID drive capacitive loads, and what is its phase margin?
TLV2455ID maintains stability into 1 nF capacitive loads with a measured phase margin of 56° (at RL = 10 kΩ, CL = 1000 pF), as documented in the Operating Characteristics table. This allows direct driving of ADC input capacitors and long PCB traces without external isolation resistors - a key advantage over older micropower op-amps that require >1 kΩ series resistance for stability.
