Product details
Overview
TLV2452CP 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, 23 µA/channel supply current, ±10 mA output drive, 20 µV typical input offset voltage, and operates from 2.7 V to 6 V - enabling precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2452CP datasheet, TLV2452CP pinout, TLV2452CP application, or TLV2452CP equivalent, this page provides verified package mapping (8-pin PDIP), confirmed rail-to-rail I/O behavior, shutdown-inactive status, real-world noise performance (49 nV/√Hz), and validated alternatives for low-power dual op-amp replacement scenarios.
Technical Context
The TLV2452CP 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 support stable unity-gain buffering and low-frequency amplification without phase reversal.
It features 106 dB power supply rejection ratio (PSRR), 80 dB common-mode rejection ratio (CMRR), and 10⁹ Ω differential input resistance - ensuring robust operation in noisy single-supply environments such as patient monitoring analog front-ends and sensor signal chains where supply ripple and common-mode interference are critical concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports direct connection to single-cell Li-ion (3.0–3.6 V) or two-cell alkaline (3.0–3.2 V) batteries without regulation. |
| Supply Current per Channel | 23 µA (typ) - enables multi-year battery life in always-on wearable health monitors. |
| Gain-Bandwidth Product | 220 kHz - sufficient for ECG lead-off detection, thermistor amplification, and bridge sensor conditioning up to ~20 kHz. |
| Input Offset Voltage | 20 µV (typ) - minimizes DC error in high-gain sensor interfaces (e.g., 1000× strain gauge amps). |
| Output Drive Capability | ±10 mA - drives 10 kΩ loads to rail while maintaining linearity, suitable for driving ADC reference buffers or DAC output stages. |
| Rail-to-Rail I/O | Yes - full dynamic range utilization at 3 V supply, maximizing SNR in low-voltage data acquisition systems. |
| PSRR | 106 dB - rejects >99.9% of 50/60 Hz supply ripple, critical for mains-powered portable instruments. |
Pinout & Package
TLV2452CP is housed in an 8-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting. Pin 1 is located at the left end of the top row when viewing the top marking side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - delivers rail-to-rail buffered or amplified signal to downstream circuitry. |
| 2 | 1IN− | Inverting input of Channel 1 - accepts feedback network for closed-loop gain configuration. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - connects to sensor, reference, or signal source with minimal input bias current (0.9 nA typ). |
| 4 | GND | Analog ground reference - must be tied to system AGND plane with low-impedance path to minimize noise coupling. |
| 5 | 2IN+ | Non-inverting input of Channel 2 - independent input node for dual-sensor or differential pair processing. |
| 6 | 2IN− | Inverting input of Channel 2 - supports independent gain-setting resistors per channel. |
| 7 | 2OUT | Output of Channel 2 - fully independent output stage; no crosstalk (< −90 dB at 1 kHz). |
| 8 | VDD+ | Positive supply rail - accepts 2.7–6 V; no internal reverse-polarity protection required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full 0–VDD signal swing at both inputs and outputs, maximizing usable dynamic range in 3-V systems. |
| Ultralow 23 µA/channel supply current | Reduces quiescent power to 69 µW at 3 V, extending battery life in continuous-monitoring devices. |
| 220 kHz gain-bandwidth with 0.11 V/µs slew rate | Supports stable unity-gain follower operation and accurate low-frequency amplification without instability. |
| 106 dB PSRR and 80 dB CMRR | Ensures immunity to supply noise and common-mode interference in unshielded medical sensor cables. |
| Specified over −40°C to 125°C (I-suffix) and 0°C to 70°C (C-suffix) | TLV2452CP (C-suffix) is rated for commercial temperature range, suitable for indoor portable equipment. |

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 |
|---|---|---|---|
| TLV2452IDR | Same electrical specs but in 8-pin MSOP package; rated for −40°C to 125°C industrial range. | Required for extended-temperature industrial sensors or automotive cabin modules. | Select TLV2452IDR when operating ambient exceeds 70°C or PCB space constraints demand surface-mount packaging. |
| MCP6022-I/P | Higher 1 MHz GBW and 2.3 V/µs slew rate; 100 µA/channel supply current; same 8-pin PDIP footprint. | Better suited for higher-speed sensor interfaces (e.g., piezoelectric vibration sensing) where bandwidth >200 kHz is needed. | Choose MCP6022-I/P only if additional speed justifies 4.3× higher quiescent current; verify layout compatibility with identical pinout. |
Compared with TLV2452CP, TLV2452IDR offers identical performance in a smaller MSOP package with wider temperature rating, while MCP6022-I/P trades ultralow power for higher speed - making TLV2452CP optimal for battery-critical, low-bandwidth precision sensing where every microamp matters.

FAQ
What is the operating temperature range for TLV2452CP?
The TLV2452CP carries the 'C' suffix, specifying an operating free-air temperature range of 0°C to 70°C. This makes it suitable for commercial-grade portable electronics such as handheld diagnostic tools and consumer health monitors used in controlled indoor environments. It is not rated for extended industrial or automotive temperature ranges - for those applications, TI offers the TLV2452ID variant.
Does TLV2452CP include a shutdown function?
No, TLV2452CP does not include a shutdown function. The TLV2452 device variant lacks a SHDN pin; only TLV2450, TLV2453, and TLV2455 members of the family feature shutdown capability. TLV2452CP remains fully active whenever powered within its 2.7–6 V supply range, drawing 23 µA per channel continuously. For shutdown functionality in a dual op-amp, consider TLV2453CP instead.
What is the maximum capacitive load TLV2452CP can drive stably?
TLV2452CP maintains stability with capacitive loads up to 1000 pF when configured as a unity-gain follower, as confirmed by phase margin measurements of 56° at that load (Figure 24, datasheet SLOS218F). For loads exceeding 1000 pF or for higher-gain configurations, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to preserve phase margin and prevent oscillation.
Can TLV2452CP operate from a single 3.3-V supply?
Yes, TLV2452CP is fully specified and characterized for operation from a single 3.3-V supply. Its 2.7–6 V VDD range includes 3.3 V, and all key parameters - including rail-to-rail input common-mode range (0 V to 3.3 V), output swing (within 250 mV of rails at 2.5 mA), 220 kHz gain-bandwidth, and 23 µA supply current - are guaranteed at this voltage per the datasheet's recommended operating conditions and electrical characteristics tables.
Is TLV2452CP pin-compatible with other dual op-amps in PDIP-8 packages?
TLV2452CP follows the industry-standard dual op-amp pinout for PDIP-8: pins 1/7 = outputs, 2/6 = inverting inputs, 3/5 = non-inverting inputs, 4 = GND, 8 = VDD+. This matches LM358, TLC272, and MCP6022 pinouts. However, functional compatibility requires verification of input bias current, offset voltage, and supply current - TLV2452CP's 0.9 nA IIB and 20 µV VIO differ significantly from LM358's 45 nA and 2 mV, so direct substitution may affect precision performance.
