Product details
Overview
TLV2455AIDR 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 20 µV typical input offset voltage across 2.7 V to 6 V operation - enabling precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2455AIDR datasheet, TLV2455AIDR pinout, TLV2455AIDR application, or TLV2455AIDR equivalent, key selection criteria include shutdown current (16 nA/ch), rail-to-rail swing under 2.5-mA load, −40°C to 125°C industrial temperature rating, TSSOP-16 package compatibility, and verified performance at 3 V single-supply operation.
Technical Context
The TLV2455AIDR 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). Its internal architecture supports stable unity-gain operation with 56° phase margin into 1000 pF capacitive loads and achieves 220 kHz gain-bandwidth at 5 V while consuming only 23 µA per channel.
Shutdown functionality is implemented via dedicated SHDN pins (pins 1/2 and 3/4) that place outputs in high-impedance state and reduce total quiescent current to 16 nA per channel. The device is fully specified across −40°C to 125°C and supports both single-supply (2.7–6 V) and split-supply (±1.35–±3 V) configurations.

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 |
|---|---|---|---|
| TLV2455IPW | Same electrical specs, TSSOP-16 package without tape-and-reel suffix; no R suffix | No functional difference; identical pinout and performance; differs only in packaging format | Select TLV2455IPW for manual prototyping or low-volume assembly where reel packaging is unnecessary |
| MCP6004T-I/ST | Higher supply current (100 µA/ch), lower GBW (1 MHz), no shutdown function, same TSSOP-14 pin count but different pin mapping | Lacks independent shutdown control and rail-to-rail input; requires higher supply voltage headroom | Choose MCP6004T-I/ST only if higher speed is required and shutdown capability is not needed |

FAQ
What is the operating temperature range for TLV2455AIDR?
The TLV2455AIDR is rated for operation from −40°C to +125°C, meeting industrial and extended-temperature requirements. This specification is validated across all electrical parameters in the official TI datasheet SLOS218F, including input offset voltage, supply current, and gain-bandwidth product - making TLV2455AIDR suitable for under-hood automotive sensors and factory-floor instrumentation.
Does TLV2455AIDR support true rail-to-rail input and output?
Yes, TLV2455AIDR supports rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swings to within 250 mV of each rail at 2.5 mA load). This capability is explicitly confirmed in the device description and electrical characteristics tables of the TI datasheet SLOS218F, enabling full-scale signal utilization in 3 V systems without external level-shifting circuitry.
How does the shutdown feature work on TLV2455AIDR?
TLV2455AIDR has two independent shutdown pairs: pins 1/2 control Channels 1 and 2; pins 15/16 control Channels 3 and 4. Driving either SHDN pin above 2 V (with VDD = 5 V) places the associated amplifiers' outputs in high-impedance state and reduces their supply current to 16 nA per channel. This behavior is documented in the "Electrical Characteristics" table under IDD(SHDN) in the TI SLOS218F datasheet.
What package type is used for TLV2455AIDR?
TLV2455AIDR uses the TSSOP-16 package (PW suffix), measuring 5.0 mm × 4.4 mm with 0.65 mm lead pitch. This is confirmed in the "TLV2454 and TLV2455 AVAILABLE OPTIONS" table of the TI datasheet SLOS218F, where TLV2455AIDR is explicitly listed under the PW column for −40°C to 125°C operation.
What is the typical input offset voltage for TLV2455AIDR?
The typical input offset voltage for TLV2455AIDR is 20 µV at 25°C, as specified in the "Electrical Characteristics" table of the TI datasheet SLOS218F under the TLV245xA row. Maximum offset is 1300 µV across the full −40°C to 125°C temperature range, supporting precision applications such as medical sensor front-ends and high-resolution data acquisition.
