Product details
Overview
TLV2452IP from Texas Instruments is a dual 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, and 23 µA/channel supply current 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 TLV2452IP datasheet, TLV2452IP pinout, TLV2452IP application, or TLV2452IP equivalent, key selection criteria include its 8-pin PDIP package, −40°C to 125°C industrial temperature range, shutdown-inactive design (no SHDN pin), and rail-to-rail swing capability at micropower consumption.
Technical Context
The TLV2452IP operates as a dual-channel voltage amplifier with fully differential input stage and push-pull output stage, supporting rail-to-rail common-mode input (0 V to VDD) and output (within 250 mV of rails at 2.5 mA load). Its 220 kHz gain-bandwidth product and 0.11 V/µs slew rate are specified at VDD = 5 V, RL = 10 kΩ, CL = 150 pF.
No internal shutdown control is implemented: the TLV2452 variant lacks SHDN pins entirely, distinguishing it from TLV2450/2453/2455. It is fully characterized at 3 V and 5 V across −40°C to 125°C, with input offset voltage ≤1000 µV (max) and PSRR ≥106 dB at 5 V.
Key Specifications

Pinout & Package
TLV2452IP uses an 8-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting. Pin 1 is identified by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Channel 1 output - delivers amplified signal with rail-to-rail swing |
| 2 | 1IN− | Inverting input for channel 1 - accepts feedback network for closed-loop gain |
| 3 | 1IN+ | Non-inverting input for channel 1 - connects to sensor or reference signal |
| 4 | GND | Analog ground reference - must be low-impedance return path for both channels |
| 5 | VDD+ | Positive supply - powers both amplifiers; no separate negative rail required |
| 6 | 2IN+ | Non-inverting input for channel 2 - electrically isolated from channel 1 inputs |
| 7 | 2IN− | Inverting input for channel 2 - supports independent feedback configuration |
| 8 | 2OUT | Channel 2 output - identical performance and drive capability as pin 1 |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2452IDR | Same electrical specs; 8-pin MSOP package (3 mm × 3 mm), surface-mount only | Required for space-constrained PCBs; not suitable for through-hole prototyping or high-reliability vibration environments | Select when board area is critical and reflow assembly is available |
| OPA2340UA | Higher 5.5 MHz GBW, 200 µA/channel supply current, same 8-pin SOIC package | Better for higher-frequency filtering (>100 kHz); trades 9× higher current for bandwidth - unsuitable for multi-year battery life | Select when bandwidth >1 MHz is required and power budget allows >100 µA/channel |

FAQ
What is the operating temperature range for TLV2452IP?
The TLV2452IP 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 SLOS218F datasheet, where the "I-suffix" designation (as indicated by the "I" in TLV2452IP) explicitly defines this extended thermal specification. The device maintains full parameter compliance across this entire range.
Does TLV2452IP include a shutdown feature?
No, TLV2452IP does not include a shutdown feature. Unlike TLV2450, TLV2453, or TLV2455, the TLV2452 variant has no SHDN pin - its pinout consists solely of two independent op-amp channels (pins 1–3 and 6–8), GND (pin 4), and VDD+ (pin 5). This is clearly shown in the "TLV245x PACKAGE PINOUTS" diagram on page 3 of the SLOS218F datasheet, where TLV2452 is depicted without any shutdown terminals.
What package type is used for TLV2452IP?
TLV2452IP uses an 8-pin plastic DIP (dual in-line package) with 0.3-inch body width and through-hole leads. The "P" suffix in the part number explicitly denotes the PDIP package, as documented in TI's packaging nomenclature guide and confirmed in the "TLV2452 and TLV2453 AVAILABLE OPTIONS" table on page 2 of the SLOS218F datasheet, where "TLV2452IP" is listed under the "PLASTIC DIP (P)" column.
What is the maximum input offset voltage for TLV2452IP?
The maximum input offset voltage for TLV2452IP is 1000 µV over the full operating temperature range of −40°C to +125°C. This value is specified in the "Electrical Characteristics" tables on pages 5 and 7 of the SLOS218F datasheet under "TLV245xA" grade (the "I" suffix corresponds to "A" grade), where VIO (max) = 1000 µV is guaranteed at TA = −40°C to 125°C and VDD = 3 V or 5 V.
Can TLV2452IP operate from a 2.7 V supply?
Yes, TLV2452IP is fully specified to operate from a minimum supply voltage of 2.7 V, as stated in the "Recommended Operating Conditions" table on page 4 of the SLOS218F datasheet. All key parameters - including gain-bandwidth, output drive, and rail-to-rail operation - are guaranteed across the full 2.7 V to 6 V range, enabling direct use with single LiFePO₄ cells or regulated 3.3 V supplies.
