TLV2452CP - Dual 6V RRIO Op Amp | Texas Instruments
MPN： TLV2452CP ✓ 啟用中TLV2452CP 概覽
An operational amplifier is an analog semiconductor that amplifies the voltage difference between its differential inputs while providing high input impedance and low output impedance. The TLV2452CP belongs to the rail-to-rail input and output operational-amplifier family within the broader voltage-feedback amplifier and analog signal-processing hierarchy. Rail-to-rail operation allows input and output voltage swings to approach the supply rails, making this amplifier useful in battery-powered and compact embedded systems.
The dual configuration provides two independent amplifier channels in one package, reducing board area when a system needs matched or simultaneous analog functions. The 220 kHz gain-bandwidth product is suitable for low-frequency sensor conditioning, audio pathways, and general-purpose signal processing. Its 23 µA quiescent current per channel reduces supply demand in battery-operated equipment, while rail-to-rail input capability improves dynamic range when the signal approaches either supply rail.
The TLV2452 family also includes shutdown functionality, allowing the amplifier channels to be disabled when they are not required. Although the TLV2452CP is a commercial-temperature variant in the PDIP package, shutdown control, offset voltage, common-mode behavior, and output-current capability should be checked against the complete operating requirements before committing a design. The 8-pin PDIP format provides a large lead pitch, useful for prototypes, education, repair, and applications where through-hole assembly is preferred over fine-pitch surface-mount packaging.
Typical applications include portable instrumentation, low-voltage sensor interfaces, battery-powered monitoring, audio input conditioning, and industrial control modules. Two channels can implement differential signal conditioning, active filtering, level shifting, transimpedance buffering, or independent gain stages. The low quiescent current is particularly useful when average standby power matters more than high-frequency closed-loop performance.
The principal design trade-off is speed. A 220 kHz amplifier favors low-power and compact analog conditioning rather than high-bandwidth signal processing. Designers should verify source impedance, output-load compatibility, settling requirements, noise performance, and stability around the selected gain before finalizing the external resistor and capacitor network.
This product record combines the manufacturer's device specifications with practical guidance on package selection, thermal and layout considerations, low-power operation, drop-in family options, and design trade-offs. It also identifies where application-specific electrical details require confirmation from the manufacturer datasheet before production release.

典型應用
TLV2452CP 適用於 6 應用s: Battery-Powered Sensor Conditioning, Portable Medical Signal Conditioning, Industrial Process Signal Interface, Low-Frequency Active Filter, Audio Preamplifier and Buffer, IoT Edge Sensor Node.
Battery-Powered Sensor Conditioning
The TLV2452CP fits low-power sensor interfaces because each dual-amplifier channel consumes 23 µA of quiescent current while providing a 220 kHz gain-bandwidth product. Its rail-to-rail input stage helps preserve signal range in single-supply systems, and the rail-to-rail output allows the conditioned voltage to approach the available supply limits. Two channels can amplify and filter one differential sensor output or condition two independent sensors. Check the source impedance, signal bandwidth, capacitive load, and output-swing requirements against the final sensor specification.
推薦
Portable Medical Signal Conditioning
The TLV2452CP can serve as a low-power front end for portable biomedical monitoring when the selected signal bandwidth is below its 220 kHz gain-bandwidth capability. The dual rail-to-rail input and output architecture supports compact single-supply instrumentation, while 23 µA per channel limits continuous demand in battery-operated equipment. Its two channels can form a difference amplifier for a bridge sensor. Medical designs still require application-specific isolation, safety, noise, leakage, and qualification review beyond the basic amplifier specifications.
推薦
Industrial Process Signal Interface
The TLV2452CP is suitable for low-frequency industrial process signals that require rail-to-rail input and output operation in a compact dual-amplifier package. A 220 kHz gain-bandwidth product supports moderate-bandwidth sensing and control paths, while 23 µA per channel is useful in distributed sensor nodes with limited power budgets. The dual channels can handle differential sensing and level conditioning. Designers should verify common-mode limits, input protection, noise performance, settling, and the allowable error budget for each industrial measurement range.
推薦
Low-Frequency Active Filter
The TLV2452CP can implement active filters and buffering stages for low-frequency audio or control signals because it provides two amplifiers, rail-to-rail input and output operation, and a 220 kHz gain-bandwidth product. The 23 µA quiescent current per channel favors portable or space-constrained filter blocks. A dual topology can create a second-order filter, transimpedance stage, or difference amplifier. Confirm the required Q, gain-bandwidth margin, component tolerance, noise, output-current capability, and phase margin for the selected feedback network.
推薦
Audio Preamplifier and Buffer
The TLV2452CP is appropriate for low-level audio buffering where low power, dual-channel operation, and rail-to-rail swing are more important than high audio-bandwidth bandwidth. Its 220 kHz gain-bandwidth product covers many low-frequency preamplifier and routing functions, and 23 µA per channel reduces battery consumption. One channel can amplify an audio input while the other buffers the return or drives a subsequent stage. Verify input-referred noise, distortion, slew rate, load impedance, and shutdown-control polarity before using it in a signal path.
推薦
IoT Edge Sensor Node
The TLV2452CP can condition the analog inputs of a compact IoT sensor node while keeping both channel current and package footprint modest. Rail-to-rail operation supports low-voltage sensor ranges, and the dual configuration can amplify two inputs or form a differential channel. The 23 µA per-channel quiescent current is valuable in devices that spend significant time between wireless transmissions. The amplifier is not intended for high-speed data conversion front ends, so its 220 kHz bandwidth and settling behavior must exceed the node's measurement bandwidth.

主要差異化特點
- Combines dual-channel operation with very low quiescent current (對比TLV2452IP)
- Rail-to-rail input and output in a through-hole package (對比TLV2452AIP)
- Dual amplifier reduces discrete package count (對比TLV2452CP)
設計說明
Keep the input, output, feedback, and bypass connections short, especially when the source impedance is high. Place the supply bypass capacitor close to pin 8, and connect the negative supply reference at pin 4 with a low-impedance return path. Because the device is intended for low-frequency operation, long PCB traces can add parasitic capacitance that alters the feedback network and may affect stability.
The TLV2452CP consumes 23 µA of quiescent current per channel, but input and output currents, divider loading, and external circuitry can increase the total demand. Confirm the regulator's minimum load behavior, bypass-capacitor effective capacitance, and shutdown-state current before estimating battery life. Use a supply that remains within the 6 V maximum rating while satisfying the lower operating-supply requirement stated in the datasheet.
Do not select the amplifier solely from its 220 kHz gain-bandwidth figure. At higher closed-loop gains, usable bandwidth and phase margin can be lower, while large capacitive loads can cause instability. Check output-swing limits against the signal, confirm input common-mode range for every rail condition, and validate the final resistor and capacitor values with an appropriate circuit simulator and bench measurements.
The 8-pin PDIP package is well suited to prototypes and repair work because its lead pitch simplifies probing and manual assembly. Preserve a consistent ground reference around both amplifier channels and avoid routing high-current return paths between the input pins and their source devices. If shutdown control is used, keep its trace away from sensitive input nodes and account for logic levels during startup and power-down.
