TLV2404CN - 16V Quad Micropower RRIO Op Amp | TI
MPN： TLV2404CN ✓ 啟用中TLV2404CN 概覽
An operational amplifier is a voltage-controlled differential amplifier used to amplify small signals, buffer sensor outputs, perform analog calculations, and drive downstream circuits. The quad TLV2404 belongs to the operational-amplifier hierarchy within analog and mixed-signal semiconductors. Its four channels can reduce external component count and simplify PCB routing compared with four separate single amplifiers, while its micropower positioning supports battery-powered and always-on equipment.
Key features include four rail-to-rail input and output amplifiers in one package, a 16 V device rating, and a 5.5 kHz gain-bandwidth product highlighted by Texas Instruments. The rail-to-rail input characteristic supports signal operation across much of the supply range, while rail-to-rail output capability helps preserve output swing near the supply rails. These characteristics are useful in portable sensor interfaces, low-frequency filter stages, and small-signal conditioning circuits.
The TLV2404CN is the standard general-purpose TLV2404 configuration identified for a 14-pin PDIP package. According to the manufacturer product page, the family is designed for 2.7 V-class operation as well as higher supply voltages. Its low bandwidth makes it appropriate for energy harvesting, battery monitoring, portable instrumentation, and other applications where high-frequency performance is unnecessary. The through-hole package also supports prototypes, educational platforms, and manually assembled industrial control boards.
Typical uses include four-channel sensor conditioning, low-pass and high-pass active filters, transimpedance stages with suitable external biasing, threshold comparators with added hysteresis, and low-frequency signal generators. In each case, resistor and capacitor values determine the practical bandwidth and noise behavior, so simulation and measurement should confirm stability, output swing, and input common-mode limits.
For PCB design, route each input and output directly to its corresponding DIP pin, maintain short feedback paths, and place input-sensing traces away from switching nodes. Because the amplifier operates at low bandwidth, bypassing and grounding are often more important than high-speed impedance matching. Check the manufacturer pin-description table before assigning functions to the 14 pins.
This product page combines the exact manufacturer and distributor identifiers with practical guidance on package reuse, low-power analog design, and four-channel layout. It also identifies where quotation, lifecycle, and detailed pin verification should be performed before production release.

典型應用
TLV2404CN 適用於 6 應用s: Battery-Powered Sensor Conditioning, Portable Instrumentation, Low-Frequency Active Filters, Industrial Threshold and Control Circuits, IoT Edge Sensing, Audio and Communication Front Ends.
Battery-Powered Sensor Conditioning
The TLV2404CN fits battery-powered sensor conditioning because it combines four micropower amplifier channels with a 5.5 kHz gain-bandwidth product and rail-to-rail input capability. One channel can amplify a sensor output, another can form an active filter, and the remaining channels can provide threshold or buffer functions. This reduces package count in a compact mixed-signal board. The principal design trade-off is bandwidth: the amplifier is intended for slowly varying signals rather than waveforms requiring high slew rate or wide closed-loop bandwidth.
推薦
Portable Instrumentation
The four amplifier channels in the TLV2404CN are useful in portable instrumentation that must process several low-frequency analog inputs in a limited board area. Rail-to-rail input operation helps preserve signal range near the supply limits, while the 14-pin PDIP package simplifies prototypes and manually assembled laboratory equipment. The 5.5 kHz gain-bandwidth product suits temperature, pressure, position, and biochemical sensor signals. Designers should verify input bias current, offset, noise, and settling time before specifying the smallest measurement range.
推薦
Low-Frequency Active Filters
The TLV2404CN can implement multiple low-frequency active-filter stages when each amplifier is assigned a different section of a signal chain. Its 5.5 kHz gain-bandwidth product provides ample loop gain for modest filter bandwidths around low-frequency sensor and control signals. Four channels allow a fourth-order or more complex filter to be built without using four separate packages. Component tolerances, op-amp noise, and the selected closed-loop topology should be simulated because gain-bandwidth alone does not determine filter accuracy or phase margin.
推薦
Industrial Threshold and Control Circuits
The TLV2404CN supports industrial threshold, comparison, and slow-control functions where multiple analog signals must be conditioned without a high-speed data converter. Rail-to-rail output capability helps produce useful logic-level transitions near the operating supply, and the quad topology provides spare channels for reference, hysteresis, or control-loop amplification. Through-hole assembly is convenient for industrial controller prototypes. Production designs should verify supply tolerance, common-mode range, output drive, and the manufacturer’s operating-temperature limits.
推薦
IoT Edge Sensing
The TLV2404CN can condition outputs from low-power IoT edge sensors that vary slowly and require several buffered channels. A quad amplifier can support excitation, signal conditioning, filtering, and threshold detection before an ADC samples the result. Its 5.5 kHz bandwidth matches many environmental and occupancy sensing workloads while avoiding the power cost of a high-speed amplifier. Because the package is a 14-pin PDIP, it is especially suitable for prototypes; a surface-mount redesign should be considered for compact production IoT hardware.
推薦
Audio and Communication Front Ends
The TLV2404CN can serve low-frequency audio or communication front ends when four channels are needed for input buffering, gain stages, anti-alias filtering, or output driving. Its rail-to-rail input and output architecture can improve signal utilization at low supply voltages, while the 5.5 kHz gain-bandwidth product is appropriate for voice-band and low-rate modulation rather than high-fidelity wideband audio. Designers should evaluate distortion, output drive, noise, and stability with the intended source impedance and load.

主要差異化特點
- Four amplifier functions in one through-hole package (對比TLV2402ID)
- Rail-to-rail input and output signal range (對比TLV2474AQDRG4Q1)
- Optimized for low-bandwidth, low-power analog channels (對比OPA132UA)
設計說明
Connect supply bypass capacitors close to the V+ and V- pins, and route those connections through low-impedance copper rather than through analog signal traces. Place each feedback resistor and compensation capacitor beside its amplifier pins to minimize loop area. Because the TLV2404CN has a 5.5 kHz gain-bandwidth product, slow signals do not require high-speed routing, but long input traces can still increase noise pickup and offset errors.
Do not treat the rail-to-rail description as permission to exceed the manufacturer input common-mode or output-swing limits. Check the exact limits at the selected supply voltage and load. Also confirm whether the chosen circuit requires input bias-current compensation, because source resistance interacting with input bias current can create output errors in high-impedance sensor interfaces.
Battery-powered designs should calculate the total amplifier supply demand from four channels, leakage-sensitive sensor biasing, and external circuitry. Confirm that the regulator can meet the required load transient while maintaining the TLV2404CN operating supply. Do not substitute a lower-dropout regulator without checking startup behavior, ground reference, output-noise coupling into the amplifier, and the added loss of headroom at the battery's minimum voltage.
Keep the four analog channels logically separated when sensitive signals are present, and avoid routing an input channel adjacent to a high-current output or switching-supply trace. Use a continuous ground reference beneath the DIP footprint where the board construction permits it. For low-level sensor inputs, use short guarded traces and consider a dedicated return path to prevent output-current voltage drops from appearing as input-referred errors.
