TLV9064SIRTER 概要
An operational amplifier (op amp) is a high-gain DC-coupled electronic voltage amplifier with differential inputs and a single-ended output, used as a fundamental building block in analog signal conditioning. The TLV9064 belongs to the broader category of CMOS op amps (using CMOS input stages for low bias current) and the rail-to-rail family, which can swing its output to within millivolts of both supply rails. This category sits within the integrated circuits hierarchy: op amp -> amplifier IC -> analog IC -> semiconductor IC -> electronic component.
Key specifications include a unity-gain bandwidth of 10 MHz, low input offset voltage of ±0.3 mV (typical), broadband input voltage noise of 10 nV/√Hz, input bias current of 0.5 pA, and quiescent current of 538 µA per channel. The amplifier is unity-gain stable, capable of driving large capacitive loads, and incorporates internal RFI/EMI rejection filtering for robust operation in noisy environments.
The TLV9064 uses a CMOS process enabling rail-to-rail input common-mode range and rail-to-rail output swing. Shutdown logic is implemented per-channel, allowing unused channels to be placed in a high-impedance low-Iq state. According to the manufacturer datasheet, internal RFI filters suppress AM-band interference without external components, simplifying PCB layout in cost-sensitive applications.
Typical applications include signal conditioning in cost-sensitive consumer IoT sensors, low-side current sensing in battery chargers, active filtering in audio front-end paths, photodiode transimpedance stages, and ADC driver / buffer circuits for portable instrumentation. The wide supply range and shutdown feature also make it suitable for always-on industrial sensor interfaces.
When designing with this device, ensure stable operation by following the datasheet recommended feedback network for unity-gain stability, especially when driving large capacitive loads. Per-channel shutdown pins should be tied to VCC through a pull-up if shutdown is unused, otherwise the input may float and place the channel in an undefined state.

主な用途
TLV9064SIRTER の用途: 7 件s: Battery-Powered IoT Sensor Signal Conditioning, ADC Driver / Buffer for Multichannel Data Acquisition, Audio Front-End Active Filter Stages, Low-Side Current Sense Amplifier, Photodiode Transimpedance Amplifier (TIA), Industrial Sensor Signal Conditioning, Cost-Sensitive Consumer Electronics Active Filtering.
Battery-Powered IoT Sensor Signal Conditioning
The TLV9064SIRTER's 1.8 V to 5.5 V single-supply range, 538 µA per-channel quiescent current, and per-channel shutdown pins make it ideal for always-on IoT sensor signal conditioning in battery-powered nodes. The 10 MHz GBW comfortably handles environmental sensor bandwidths (temperature, humidity, pressure, gas) while the CMOS 0.5 pA input bias current avoids loading high-impedance sensor sources. The internal RFI/EMI filter rejects AM-band interference common in residential and industrial wireless environments. A typical circuit places one channel as a precision gain stage for a Wheatstone-bridge sensor, with the remaining channels buffering ADC inputs or active-filtering supply noise. Per-channel shutdown reduces total Iq to sub-µA when sensors are sampled infrequently, extending coin-cell lifetime.

ADC Driver / Buffer for Multichannel Data Acquisition
The TLV9064SIRTER's 10 MHz GBW and rail-to-rail input/output capability suit it as a buffer or driver for 12-bit to 16-bit ADCs in multichannel data-acquisition systems. The ±0.3 mV typical input offset preserves ADC dynamic range, while the 10 nV/√Hz noise floor contributes minimal jitter at the analog front-end. Each of the four channels can drive ADC inputs directly with the proper anti-alias filter network, and unused channels can be placed in shutdown to reduce system Iq. The WQFN-16 (RTE) 3x3 mm footprint places all four amps in a tight area next to the ADC, minimizing board area and trace length for low-distortion performance. Per the manufacturer datasheet, the device is unity-gain stable even with large capacitive ADC load.
おすすめ
Audio Front-End Active Filter Stages
The TLV9064SIRTER's 10 MHz GBW (well above the 20 kHz audio band) and rail-to-rail output drive make it a strong choice for active filter stages in audio front-ends, including Sallen-Key low-pass, high-pass, and band-pass topologies. The 0.5 pA CMOS input bias preserves high-impedance filter-element values without DC error, and the internal RFI filter rejects AM-band interference entering through audio cables. Each quad package can implement a stereo two-pole filter plus auxiliary channels for headphone amplifiers or microphone bias networks. The shutdown pin allows the entire filter chain to be powered down during deep-sleep audio standby, supporting headphones with always-listening wake-word features without continuous Iq overhead.
おすすめ
Low-Side Current Sense Amplifier
The TLV9064SIRTER works as a low-side current-sense amplifier in battery chargers, motor controllers, and power-path monitors when configured in a differential gain stage across a shunt resistor. The rail-to-rail input common-mode range allows the sense node to swing arbitrarily close to ground, and the 0.5 pA input bias avoids disturbing the shunt node bias. The 10 MHz GBW supports high-bandwidth current-loop monitoring for step-response and short-circuit detection. The per-channel shutdown is useful in redundant current-sensing architectures where one amplifier can be powered down for diagnostic isolation without disturbing the primary channel.
おすすめ
Photodiode Transimpedance Amplifier (TIA)
The TLV9064SIRTER's sub-pA input bias current and 10 MHz GBW suit it for photodiode transimpedance stages in optical sensors, smoke detectors, and pulse-oximetry front-ends. The CMOS input stage does not contribute significant bias current at room temperature, preserving the TIA's DC accuracy and minimizing ambient-light floor. The 10 nV/√Hz broadband noise density sets the TIA noise floor and bandwidth product for low-light detection. Four channels in one package allow multi-wavelength photodiode conditioning (e.g., red/infrared for SpO2) within a 3x3 mm footprint, while shutdown pins cut quiescent current between LED pulses.
おすすめ
Industrial Sensor Signal Conditioning
The TLV9064SIRTER's -40 °C to +125 °C operating range and 1.8 V to 5.5 V supply make it ideal for industrial sensor signal conditioning in factory automation, process control, and HVAC monitoring. The internal RFI/EMI filter rejects sub-1 GHz interference common near motor drives and switching relays in industrial cabinets. The rail-to-rail I/O handles 24 V industrial bus signals after resistive scaling, allowing direct interface to PLC analog modules. The per-channel shutdown enables energize-on-demand sensing for low-duty-cycle sensors, reducing cabinet thermal load and saving energy in densely populated control panels.
おすすめ
Cost-Sensitive Consumer Electronics Active Filtering
The TLV9064SIRTER's cost-optimized CMOS architecture and tight WQFN-16 footprint make it a strong fit for cost-sensitive consumer electronics active filters in white goods, toys, and household appliances. The 10 MHz GBW is overkill for audio-frequency filtering but allows designers to use the same op amp for both audio stages and the wideband anti-alias filters in simpler consumer ADC interfaces. The 0.5 pA input bias current preserves the high-impedance nodes typical of touch and capacitive-sensing interfaces used in modern appliance UI. Shutdown pins are valuable for battery-operated handheld consumer devices where quiescent current directly impacts standby-time spec compliance.

設計ノート
The TLV9064SIRTER's exposed thermal pad (pin 17 / DAP) MUST be soldered to a PCB ground plane for rated thermal and electrical performance. Place input and output traces symmetrically and keep high-impedance input traces short to minimize leakage and noise pickup. Use a continuous ground plane under the WQFN-16 footprint to provide low-impedance return paths for all four amplifier channels. Per-channel supply decoupling with a 100 nF X7R ceramic capacitor placed within 2 mm of the V+ pin is recommended, with an additional 1 µF bulk capacitor on the supply node.
Each of the four channels has a dedicated shutdown pin (SHDNA, SHDNB, shared SHDNC/D). For unused shutdown pins, tie them to V+ through a 100 kΩ pull-up resistor to keep the corresponding channel active; do not leave them floating, as an undefined state may place the channel in undesired shutdown or draw excess current. Driving a shutdown pin low places that channel in high-impedance output and reduces Iq to leakage levels, useful for energize-on-demand sensing topologies.
Avoid operating the inputs beyond the rail-to-rail common-mode range, especially during input fault conditions; the CMOS input stage can phase-reverse if the input is forced more than ~0.5 V beyond either rail. For ADC-driving applications, place a 10 Ω to 100 Ω series resistor at the amplifier output to isolate capacitive ADC input loads and preserve phase margin. When driving large capacitive loads (>1 nF) directly, follow the datasheet recommended feedback capacitor values to maintain stability, otherwise oscillation may occur. Do not assume the absolute maximum ratings allow inductive kickback - use clamping diodes if switching inductive loads downstream of the amplifier output.
