TLV2450IP - 6V, 220kHz, 23µA RRIO Op Amp | Texas Instruments
料号： TLV2450IP ✓ 量产中TLV2450IP 概述
An operational amplifier is a voltage-feedback amplifier used to amplify differential signals, buffer analog nodes, or perform basic analog functions through external feedback networks. The TLV2450 belongs to the operational-amplifier hierarchy, where it combines rail-to-rail input and output capability with low quiescent current. Its power-management characteristics make it suitable for battery-operated equipment where every microamp of supply demand affects available operating time.
The principal features of the TLV2450IP include a 23 µA typical supply current per channel, 220 kHz gain-bandwidth product, rail-to-rail input and output operation, and operation from a single supply up to 6 V. The manufacturer describes the device as a single 6 V, 220 kHz, low-quiescent-current RRIO operational amplifier with shutdown capability. Shutdown support is useful when a battery-powered system needs to reduce current consumption while the amplifier is not actively processing a signal.
The family operates from a single positive supply, which simplifies circuits that cannot use negative rails. Rail-to-rail input operation allows sensing signals near either supply rail, while rail-to-rail output improves output-voltage range and can reduce the need for additional output-stage headroom. The 220 kHz gain-bandwidth product makes the amplifier appropriate for moderate-speed closed-loop stages rather than high-speed signal-path applications requiring substantially greater bandwidth.
Typical uses include portable sensor interfaces, low-current data-acquisition front ends, battery-powered monitoring, analog filtering, buffer stages, and embedded instrumentation. In a sensor circuit, the amplifier can amplify a small differential signal while keeping system current consumption low. For filter and gain-stage designs, external resistors and capacitors determine the achievable response, subject to the amplifier's gain-bandwidth and stability characteristics.
Designers should account for shutdown logic, input common-mode range, output swing, bias current, noise, and stability when assigning feedback components. Place the device close to the feedback network and maintain a stable reference connection to minimize parasitic effects. Confirm the complete electrical limits and pin configuration in the manufacturer datasheet before using the device in a new design.
This product page consolidates the verified manufacturer characteristics, package information, sourcing workflow, drop-in comparison, and practical application guidance. It supports faster component selection by separating the TLV2450IP's low-power RRIO features from the design constraints that matter in portable and instrumentation systems.

典型应用
TLV2450IP 适用于 6 应用s: Battery-Powered Sensor Interface, Portable Data Acquisition, Industrial Instrumentation Buffer, Precision Low-Frequency Filtering, Battery-Powered Environmental Monitor, Low-Power Analog Signal Conditioning.
Battery-Powered Sensor Interface
The TLV2450IP fits low-voltage sensor interfaces that require low standing current and broad input range near the supply rails. Its 23 µA typical quiescent current limits amplifier overhead in battery-powered monitoring, while rail-to-rail input operation helps preserve small sensor signals within a compact voltage range. The 220 kHz gain-bandwidth product is sufficient for common temperature, pressure, and resistive sensor conditioning stages. Shutdown can disconnect the amplifier during inactive intervals, although total battery life must also account for the sensor, pull-up networks, and external load current.
推荐
Portable Data Acquisition
The TLV2450IP can condition low-level analog channels in portable data-acquisition equipment where each active amplifier contributes directly to available battery capacity. A 23 µA typical quiescent current is appropriate for slow or intermittently sampled measurements, and shutdown capability supports duty-cycled operation. Rail-to-rail input and output behavior improves signal utilization in systems with limited supply voltage. The 220 kHz gain-bandwidth product should be matched to the required settling time, sensor bandwidth, and antialiasing-filter frequency rather than treated as a high-speed ADC driver specification.
推荐
Industrial Instrumentation Buffer
The TLV2450IP is useful as a unity-gain buffer or general-purpose gain stage in low-power industrial instrumentation. Its rail-to-rail input and output capability helps accommodate sensor and transducer signals close to the supply limits, while the single-supply operation simplifies isolated or battery-backed measurement modules. The 220 kHz gain-bandwidth product supports moderate-bandwidth sensor signals but is not intended for high-frequency measurement chains. Input bias current, offset voltage, output loading, and noise must be evaluated against the selected feedback network and sensor impedance.
推荐
Precision Low-Frequency Filtering
The TLV2450IP can implement active low-pass, high-pass, or other first-order and higher-order analog filters when the signal bandwidth is modest. Its 220 kHz gain-bandwidth product provides loop gain above the intended filter corner frequency, while 23 µA typical quiescent current favors unattended or portable monitoring systems. Rail-to-rail operation broadens usable signal range in low-voltage circuits. Component tolerances, op-amp noise, offset voltage, and the effect of the feedback network on the actual cutoff frequency should be checked during simulation.
推荐
Battery-Powered Environmental Monitor
The TLV2450IP fits environmental monitoring nodes that amplify small outputs from resistive, temperature, or gas sensors while operating from a limited energy budget. The 23 µA typical quiescent current is useful when the amplifier remains connected continuously, and the shutdown function can reduce demand during scheduled readings. Rail-to-rail input and output behavior helps maximize the usable signal range of a low-voltage sensor platform. Overall enclosure power, sensor heater power, and radio activity generally dominate system consumption, so the amplifier should be enabled only for the measurement interval when possible.
推荐
Low-Power Analog Signal Conditioning
The TLV2450IP provides a compact analog conditioning stage for systems that convert a bipolar or near-rail sensor signal into a range suitable for an ADC. Rail-to-rail input and output behavior reduces the need for an additional rail-shifting stage, while the 6 V maximum supply supports conventional low-voltage rails. The 220 kHz gain-bandwidth product and ±10 mA output-drive figure define practical limits for amplifier selection. Designers should verify common-mode range, output swing, shutdown polarity, and stable feedback ratios for the actual supply and load before release.

设计说明
Budget the TLV2450IP's 23 µA typical quiescent current as part of the continuous system load, then calculate the remaining budget for the sensor, feedback network, logic, and communications. Use the shutdown control when the measurement chain can be disabled between samples. Confirm the permitted shutdown logic and state from the family datasheet before connecting it to a system power-sequencing signal.
In an 8-pin PDIP design, route the power and ground connections directly to the device pins and keep feedback components close to the amplifier pins. Avoid long signal paths between the op amp and its resistors or capacitors, particularly when working with high-impedance sensors. Follow the manufacturer package drawing for hole size, row spacing, lead length, and pin-1 orientation.
Do not assume that rail-to-rail input and output operation means the output can reach either rail under every load. Check the datasheet's output-swing and common-mode limits for the actual supply, load, and temperature. Also verify that the intended feedback ratio remains stable within the 220 kHz gain-bandwidth product and that the 6 V maximum supply rating is never exceeded.
For high-impedance sensor sources, minimize input-node leakage and account for bias current when selecting feedback resistors. Place protection leakage paths away from sensitive inputs and use guarding techniques if necessary. If the source has appreciable capacitance, add an isolation resistor at the amplifier input and validate stability and settling behavior in simulation.
