Product details
Overview
TLV2454IN 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 TLV2454IN datasheet, TLV2454IN pinout, TLV2454IN application, or TLV2454IN equivalent, this page provides verified electrical specs, TSSOP-14 package layout, shutdown behavior, rail-to-rail dynamic range implications, and direct alternatives for low-power analog signal chain design.
Technical Context
The TLV2454IN 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), supporting single-supply operation down to 2.7 V. Its 220 kHz gain-bandwidth product and 0.11 V/µs slew rate are specified at 5 V and 3 V, with stable unity-gain performance up to 1000 pF capacitive load.
No internal shutdown function is present in the TLV2454 variant - unlike TLV2450/3/5 - confirmed by family packaging table and absence of SHDN pins in its TSSOP-14 pinout. It is fully characterized across −40°C to 125°C (I-suffix) and supports industrial-grade reliability without power-down control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - enables direct use with single Li-ion, two alkaline, or regulated 3.3 V/5 V rails without level-shifting. |
| Gain-Bandwidth Product | 220 kHz at VDD = 5 V - sufficient for DC-coupled sensor amplification, low-frequency filtering, and 12-bit ADC driver stages. |
| Supply Current per Channel | 23 µA - allows four independent op-amps to consume <100 µA total, critical for multi-channel battery life extension. |
| Output Drive Capability | ±10 mA - drives 500 Ω loads directly, eliminating need for external buffers in transducer interface circuits. |
| Input Offset Voltage | 20 µV (typ) - supports sub-100 µV system-level offset budgets in precision instrumentation amplifiers. |
| Rail-to-Rail I/O | Full swing input (0 V to VDD) and output (within 250 mV of rails at 2.5 mA) - maximizes dynamic range in 3 V systems. |
| PSRR | 106 dB - rejects supply noise effectively, reducing need for ultra-clean LDOs in mixed-signal PCB layouts. |
Pinout & Package
TLV2454IN is housed in a 14-pin TSSOP (PW) package with exposed thermal pad, rated for −40°C to 125°C operation. The package supports automated assembly and offers 0.65 mm pitch, 5.0 mm × 4.4 mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - connects to feedback network or next-stage input; rail-to-rail capable. |
| 2 | 1IN− | Inverting input of Amp A - high-impedance CMOS node; requires matched trace routing for low-noise designs. |
| 3 | 1IN+ | Non-inverting input of Amp A - same high-Z property; used for reference or sensor connection. |
| 4 | GND | Analog ground reference - must be tied to clean system ground plane; shared by all four amplifiers. |
| 5 | 4IN− | Inverting input of Amp D - dedicated channel input; no internal connection to other amps. |
| 6 | 4IN+ | Non-inverting input of Amp D - independent signal path; supports differential or single-ended configurations. |
| 7 | 4OUT | Amplifier D output - full rail-to-rail swing; usable as final buffer or filter output stage. |
| 8 | VDD+ | Positive supply rail - powers all four amplifiers; bypass capacitor required within 1 cm. |
| 9 | 3OUT | Amplifier C output - identical performance to Pins 1 and 7; enables parallel or cascaded topologies. |
| 10 | 3IN− | Inverting input of Amp C - isolated from other channels; supports multi-sensor simultaneous sampling. |
| 11 | 3IN+ | Non-inverting input of Amp C - matches Pin 3/6 electrical characteristics; maintains channel independence. |
| 12 | 2IN+ | Non-inverting input of Amp B - completes quad set; no NC or SHDN pins present. |
| 13 | 2IN− | Inverting input of Amp B - symmetric layout to Pin 2/5/10; ensures consistent layout practices. |
| 14 | 2OUT | Amplifier B output - electrically identical to other outputs; supports independent gain-setting per channel. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| TLV2474IN | Higher 2.8 MHz GBW and 1.5 V/µs slew rate; 600 µA/channel supply current - 26× higher than TLV2454IN. | Targeted at higher-speed signal chains (e.g., active filters above 100 kHz); unsuitable for micropower battery operation. | Select TLV2474IN only when bandwidth >1 MHz is required and power budget allows >2 mA total quiescent current. |
| LMV324IPW | 2.5 V to 5.5 V supply; 1 MHz GBW; 130 µA/channel; rail-to-rail output only (not input); 700 µV max VIO. | Lacks rail-to-rail input - limits common-mode range in single-supply 3 V designs; higher offset degrades precision DC accuracy. | Choose LMV324IPW for cost-sensitive, non-precision applications where input common-mode range >1 V is acceptable. |
Compared with TLV2454IN, TLV2474IN trades 26× higher power for 13× more bandwidth, while LMV324IPW reduces cost but sacrifices rail-to-rail input capability and doubles offset voltage - making TLV2454IN the optimal balance for precision, low-power, single-supply quad op-amp needs.

FAQ
What is the operating temperature range for TLV2454IN?
The TLV2454IN is rated for −40°C to +125°C operation, as indicated by the 'I' suffix in the part number. This extended industrial temperature range is validated across all key parameters including input offset voltage, supply current, and gain-bandwidth product - making TLV2454IN suitable for under-hood automotive sensors, industrial field transmitters, and outdoor medical equipment.
Does TLV2454IN include a shutdown feature?
No, TLV2454IN does not include a shutdown feature. The TLV245x family reserves shutdown capability for TLV2450, TLV2453, and TLV2455 variants only - confirmed by the family package table and absence of SHDN pins in the TLV2454 TSSOP-14 pinout. TLV2454IN draws 23 µA per channel continuously and has no enable/disable control terminal.
What package type is used for TLV2454IN?
TLV2454IN uses a 14-pin TSSOP (Thin Shrink Small Outline Package) with PW designation, featuring a 0.65 mm pin pitch and 5.0 mm × 4.4 mm body size. It includes an exposed thermal pad for enhanced heat dissipation and is RoHS-compliant - optimized for high-density PCB layouts and automated surface-mount assembly.
Can TLV2454IN operate from a 3 V supply?
Yes, TLV2454IN is fully specified and functional at 3 V supply voltage. Its rail-to-rail input and output stages operate down to 2.7 V, and all key parameters - including 220 kHz gain-bandwidth, 23 µA supply current, and ±10 mA output drive - are guaranteed across the 2.7 V to 6 V range. This makes TLV2454IN ideal for single-cell Li-ion or two-cell alkaline battery systems.
What is the maximum output current capability of TLV2454IN?
TLV2454IN delivers ±10 mA output current per channel into loads referenced to VDD or GND, as specified in the Electrical Characteristics table at VDD = 5 V. At 3 V, it sustains ±4 mA minimum - sufficient to drive 500 Ω loads directly. Short-circuit output current is rated at ±20 mA sourcing and ±12 mA sinking, ensuring robustness against transient overload conditions.
