Product details
Overview
TLV2452AIP 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, 23 µA/channel supply current, and operates from 2.7 V to 6 V. Its key role is precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2452AIP datasheet, TLV2452AIP pinout, TLV2452AIP application, or TLV2452AIP equivalent, this page provides verified package mapping (8-pin PDIP), confirmed shutdown functionality absence, rail-to-rail I/O behavior at 3 V/5 V, and real-world design trade-offs versus alternatives like TLV2462AIP and MCP6022-I/P.
Technical Context
The TLV2452AIP 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 220 kHz gain-bandwidth product and 0.11 V/µs slew rate are specified at VDD = 5 V, RL = 10 kΩ, CL = 150 pF.
It features 106 dB PSRR and 80 dB CMRR at 25°C, 5 V supply, with input offset voltage of 300–1000 µV (typ/max) across −40°C to 125°C. No internal shutdown control is present - the TLV2452AIP variant excludes the SHDN pin found on TLV2450/3/5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion (3.0–3.7 V) and two-cell alkaline (3.0–3.2 V) operation without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - enables stable unity-gain buffer or low-frequency instrumentation amplification up to ~100 kHz. |
| Supply Current per Channel | 23 µA - allows >1-year battery life in always-on sensor nodes powered by CR2032 (225 mAh). |
| Output Drive Capability | ±10 mA - drives 500 Ω loads directly (e.g., ADC reference buffers, analog multiplexer outputs). |
| Input Offset Voltage | 300 µV (typ), 1300 µV (max, −40°C to 125°C) - suitable for 12-bit precision measurement with <0.3 LSB error at 5 V full-scale. |
| Rail-to-Rail I/O | Yes - preserves full dynamic range in 3 V systems; inputs accept 0 V to VDD, outputs swing to within 250 mV of each rail at 2.5 mA. |
| Operating Temperature | −40°C to +125°C - qualified for automotive cabin and industrial motor-control feedback loops. |
Pinout & Package
TLV2452AIP is housed in 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 | OUT A | Inverting amplifier output channel A - connects directly to ADC input or filter network. |
| 2 | IN− A | Inverting input for channel A - used for feedback in inverting configurations or as summing node. |
| 3 | IN+ A | Non-inverting input for channel A - accepts sensor signals, reference voltages, or buffered sources. |
| 4 | GND | Analog ground reference - must be star-connected to system AGND to minimize noise coupling. |
| 5 | IN+ B | Non-inverting input for channel B - independent of channel A; enables dual-sensor monitoring. |
| 6 | IN− B | Inverting input for channel B - supports separate feedback paths for differential or single-ended use. |
| 7 | OUT B | Inverting amplifier output channel B - electrically isolated from OUT A; no crosstalk above −90 dB @ 1 kHz. |
| 8 | VDD+ | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3 V supply range - eliminates need for level-shifting in low-voltage microcontroller interfaces. |
| Ultralow 23 µA/channel quiescent current | Reduces system standby power by >90% vs. standard op-amps (e.g., LM358: 700 µA), critical for energy-harvesting designs. |
| 220 kHz GBW with 0.11 V/µs slew rate | Supports stable closed-loop gain ≥10 up to 20 kHz - sufficient for ECG front-end filtering and thermistor linearization. |
| 106 dB PSRR at DC | Maintains accuracy despite battery voltage sag or noisy DC-DC converter ripple - no additional LDO required. |
| Specified over −40°C to +125°C | Validated for under-hood automotive and industrial PLC environments without derating. |
Applications
| Portable Patient Monitor | Industrial Temperature Sensor Interface |
|---|---|
|
Use Scenario: Amplifying low-level thermopile or RTD bridge outputs in handheld vital sign monitors. IC Role / Device Role / Timing Role: Dual-channel instrumentation amplifier front-end - one channel for sensor signal, one for reference compensation. Use Value: Rail-to-rail I/O preserves 98% of 3 V ADC range; 23 µA/channel extends CR2032 battery life beyond 18 months. |
Use Scenario: Conditioning Pt100 RTD signals in factory-floor temperature transmitters. IC Role / Device Role / Timing Role: Precision voltage follower and excitation current buffer in 4-wire RTD circuits. Use Value: 300 µV max input offset contributes <0.3°C error at 100°C; 125°C rating ensures reliability near motors and drives. |
| Low-Power Data Acquisition Module | Wearable Biopotential Sensor |
|
Use Scenario: Multiplexed analog front-end for 8-channel environmental sensor arrays (gas, humidity, pressure). IC Role / Device Role / Timing Role: Channel-selectable gain stage and anti-aliasing buffer before SAR ADC sampling. Use Value: 220 kHz GBW supports ≤100 kSPS sampling with <0.1% settling; ±10 mA drive handles 10 kΩ ADC input impedance. |

Use Value: 51 nV/√Hz input noise ensures SNR >70 dB for 0.5–40 Hz biopotential band; rail-to-rail output avoids clipping during motion artifacts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462AIP | Higher 6.4 MHz GBW, 550 µA/channel supply current, same 8-pin PDIP package. | Used where bandwidth >100 kHz is required (e.g., active filters), but incompatible with sub-100 µA power budgets. | Select TLV2462AIP only when speed outweighs battery life - not drop-in; requires PCB layout review for thermal dissipation. |
| MCP6022-I/P | 2.8 MHz GBW, 1 mA/channel, 1.8–6 V supply, same pinout but no guaranteed 125°C operation. | Common in consumer wearables; lacks extended temperature validation for industrial deployment. | Choose MCP6022-I/P for cost-sensitive 85°C-limited designs; verify PSRR (90 dB) and offset drift (2.5 µV/°C) against TLV2452AIP specs. |
Compared with TLV2452AIP, TLV2462AIP trades 24× higher supply current for 29× greater bandwidth, while MCP6022-I/P offers mid-range performance with unverified high-temperature stability - making TLV2452AIP the sole choice for ultra-low-power, wide-temperature, precision analog sensing.

FAQ
What is the operating temperature range for TLV2452AIP?
The TLV2452AIP is rated for operation from −40°C to +125°C, as confirmed in the "Recommended Operating Conditions" table of the SLOS218F datasheet. This extended range is validated for both electrical performance and reliability, making TLV2452AIP suitable for under-hood automotive and industrial motor-control applications where ambient temperatures exceed 105°C.
Does TLV2452AIP include a shutdown pin?
No, TLV2452AIP does not include a shutdown pin. The TLV2452 device variant (including TLV2452AIP) omits the SHDN terminal present on TLV2450/3/5. This is explicitly shown in the "TLV245x PACKAGE PINOUTS" diagram on page 3 of the datasheet, where TLV2452 pinouts show no SHDN connection - confirming TLV2452AIP operates continuously when powered.
What is the maximum output current capability of TLV2452AIP?
TLV2452AIP delivers ±10 mA output current per channel, as specified in the "Electrical Characteristics" table (page 7) under "Output current" with VO = 0.5 V from rail at VDD = 5 V. This allows direct driving of 500 Ω loads - sufficient for buffering SAR ADC references or driving analog multiplexer inputs without external gain stages.
Is TLV2452AIP pin-compatible with other TLV245x variants in PDIP packages?
Yes, TLV2452AIP shares identical 8-pin PDIP pinout with TLV2452CD, TLV2452ID, and TLV2452CP - all follow the standard dual-op-amp configuration (OUT A, IN− A, IN+ A, GND, IN+ B, IN− B, OUT B, VDD+). However, it is not pin-compatible with TLV2450/3/5 due to their dedicated SHDN pins, nor with TLV2454/5 which use 14-/16-pin packages.
What is the typical input offset voltage of TLV2452AIP at room temperature?
The typical input offset voltage of TLV2452AIP at 25°C is 300 µV, as stated in the "Electrical Characteristics" table (pages 5 and 7) under "Input offset voltage" for TLV245xA grade. This value is measured at VDD = 3 V and VDD = 5 V, and remains stable across the full −40°C to +125°C range with a maximum of 1300 µV.
