LMP7721MA/NOPB

LMP7721MA/NOPB-Q1 - 3fA Input Bias Precision Op Amp | Texas Instruments

The LMP7721MA/NOPB is a single-channel precision operational amplifier from Texas Instruments featuring the industry's lowest guaranteed input bias current of 3 fA (typical), with a specified limit of plus/minus 20 fA at 25C and plus/minus 900 fA at 85C. It operates from a single 1.8V to 5.5V supply, delivers 17 MHz gain-bandwidth product, and 12.8 V/us slew rate in an 8-pin SOIC package. An operational amplifier (op amp) is a high-gain voltage amplifier with differential inputs, forming the foundation of analog signal conditioning within the amplifier IC hierarchy: operational amplifier -> precision amplifier -> analog front end -> signal chain IC. Precision amplifiers are distinguished by near-zero DC error terms - input bias current, offset voltage, and drift. The LMP7721 achieves its femtoampere-class input bias current through patent-pending input bias current cancellation circuitry, which maintains ultra-low bias current over temperature. Critically, the 8-pin SOIC uses a special pinout that isolates the amplifier inputs from the power supply and output pins. With proper board layout techniques, this unique pinout prevents PCB leakage current from reaching the input pins - a decisive advantage over conventional op amp pinouts when guarding is required. As a rail-to-rail input and output amplifier, it maximizes dynamic range in low-voltage systems while drawing low supply current, suiting battery-operated instruments. The wide supply range and high GBW allow use with electrochemical cells, photodiodes, and high-impedance sensors where even picoampere loading corrupts measurements. Typical applications include ionization chamber and electrochemical sensor front ends, photodiode transimpedance amplifiers for low-light detection, pH and dissolved-gas probe buffers, and picoammeter instrumentation. Design tip: to fully exploit the 3 fA bias current, use guard rings connected to the input-following low-impedance node and clean the PCB after assembly - flux residue and moisture can leak picoamperes that dwarf the amplifier's own bias current.

LMP8350MA/NOPB - Ultra-Low Distortion ADC Driver | Texas Instruments

The Texas Instruments LMP8350MA/NOPB is an ultra-low-distortion fully-differential precision ADC driver designed for driving high-performance analog-to-digital converters in data acquisition systems. It ships in an 8-pin SOIC (D, 3.90 mm width) package with an operating temperature range of -40C to +85C and a RoHS-compliant lead-free finish. A fully-differential ADC driver is a special-purpose amplifier that converts a single-ended or differential input into a balanced differential output optimized for the differential input stage of precision ADCs. Within the signal-chain hierarchy (ADC driver -> amplifier -> analog front end -> signal chain), it provides output common-mode control, rejects even-order harmonics, and improves common-mode noise immunity ahead of the converter. Key features include ultra-low distortion across a fully-differential signal path and three selectable operating modes controlled by a unique mode enable pin. As part of TI's PowerWise family, the high power mode is optimized for highest AC dynamic performance, while lower modes trade dynamic range for reduced power consumption - a flexibility few fixed-power differential drivers offer. The /NOPB suffix denotes a no-pull BOM with lead-free, RoHS-compliant plating suitable for global commercial and industrial builds. Technically, the differential architecture inherently cancels common-mode noise and suppresses even-order distortion, which directly benefits THD and SNR when interfacing to precision SAR and delta-sigma converters. The three-mode design lets one footprint serve both battery-powered low-power data acquisition and high-AC-performance instrumentation, differentiating the LMP8350 from conventional fixed-bias fully-differential amplifiers. Typical applications include high-speed precision data acquisition, industrial process control and PLC analog input modules, medical ultrasound front ends, communications receivers and software-defined radios, automated test equipment, and portable battery-powered instruments. Design tip: realize the datasheet ultra-low-distortion performance only with a clean, symmetrical differential PCB layout, tight supply decoupling, and correct MODE pin configuration; verify pricing as of 2026-08-30 with current distributor stock at DigiKey and Mouser.

Packaged in an 8-pin SOIC (3.90 mm width), it belongs to TI's LMP precision amplifier family and the PowerWise product line, with an operating temperature range of -40C to +85C. Note: the verified web data covers the base LMP8350MA/NOPB; the -Q1 suffix variant should be confirmed against TI ordering information. A fully-differential amplifier (FDA) is a special-purpose amplifier that processes and outputs a differential signal, converting single-ended inputs to differential outputs with excellent common-mode rejection. FDAs are the preferred interface between single-ended analog sources and differential-input ADCs because they cancel common-mode noise, improve dynamic range, and maintain balance in the signal chain. The defining feature of the LMP8350 is its unique mode-enable pin, which lets the designer choose among three operating modes that trade power consumption for dynamic performance. The high-power mode is optimized for the highest AC performance and ultra-low distortion, while lower-power modes save current in battery-powered or thermally constrained systems. As an ADC driver for data acquisition, it achieves very low harmonic distortion suitable for driving precision and high-speed converters. According to the TI datasheet (LMP8350, 36-page document), the device is engineered for driving high-performance precision ADCs in data acquisition systems. Its differential architecture, selectable power modes, and precision DC performance make it a strong fit where signal integrity is paramount. Typical applications include precision data acquisition front ends, industrial process control, test and measurement instrumentation, and medical imaging signal chains - anywhere a single-ended or differential source must drive a differential ADC input without degrading THD or SNR. Design tip: the selected power mode affects both bandwidth and distortion, so verify THD at your target frequency and gain in the chosen mode, and keep the mode pin driven from a defined logic level for deterministic startup.

LMP8640MK-H - 42V Current Sense Amp, 950kHz | Texas Instruments

The Texas Instruments LMP8640MK-H is a precision high-voltage current sense amplifier that detects small differential voltages across an external shunt resistor in the presence of high input common-mode voltages up to 42V, housed in a 6-pin SOT-23-THIN (TSOT-23-6, MK package). The device operates from a 2.7V to 12V supply and accepts common-mode inputs from -2V to 42V, with a unity-gain bandwidth of 950kHz and a slew rate of 1.8 V/us, enabling fast transient response in switching power-supply feedback loops. A current sense amplifier is a specialized analog IC that converts a small differential voltage developed across a low-value shunt resistor into a ground-referenced output proportional to load current. These devices sit in the signal-chain hierarchy between the power stage (MOSFET/IGBT switches) and the control stage (MCU/DSP/ADC), allowing tight closed-loop monitoring of motor, solenoid, and battery currents in industrial, automotive, and telecom systems. Compared with discrete op-amp current-sense solutions, integrated parts like the LMP8640 offer calibrated fixed gains, factory-trimmed offsets, and built-in EMI/RFI filtering that would otherwise consume board area and design effort. Key specifications include a fixed gain of 20 (the -H variant), input offset voltage in the sub-millivolt range, integrated EMI rejection on the input pins, and a low quiescent supply current suited to always-on monitoring. The TSOT-23-6 package provides a small 2.9 mm x 1.6 mm footprint suitable for high-density power-conversion PCBs. The wide -2V to 42V common-mode window makes the part tolerant of load-dump transients in 12V/24V automotive and industrial buses. The architecture uses a precision front-end differential pair followed by gain and output stages optimized for unidirectional or bidirectional current monitoring depending on the reference pin connection. The high 1.8 V/us slew rate preserves signal fidelity during rapid di/dt events such as inrush, PWM switching, and motor commutation. Integrated RFI filtering suppresses the high-frequency noise that would otherwise be rectified by the input stage and appear as DC error at the output. Typical applications include solenoid and valve current monitoring, motor-control phase current sensing, battery-pack charge/discurrent monitoring, 48V telecom rail current telemetry, and high-side current sensing in switching power supplies. The 42V common-mode range covers 12V/24V industrial buses with substantial transient headroom. When designing with this device, place the sense resistor close to the IC input pins and use a Kelvin connection to minimize parasitic resistance errors. The reference pin (REF) sets the output zero-current voltage; for unidirectional sensing tie REF to ground, for bidirectional sensing tie to mid-rail. Decouple VCC with a 100 nF ceramic capacitor placed within 5 mm of the supply pin.

Housed in a 6-pin SOT-23-THIN (TSOT-23-6, DDC) package, it operates from a 2.7V to 12V supply and accepts common-mode input voltages from -2V to +42V, making it ideal for high-side and low-side current monitoring in 12V, 24V, and 36V industrial buses. A current sense amplifier is an analog IC that amplifies the small differential voltage developed across a shunt resistor carrying the load current, while rejecting the large common-mode voltage present at the resistor terminals. This category sits within the broader hierarchy of operational amplifiers (op-amps) and instrumentation amplifiers, which in turn belong to the signal-conditioning family of analog ICs used in power management, motor control, and battery monitoring. The LMP8640MK-H/NOPB provides fixed internal gain (the "-H" variant specifies the gain version), eliminating the need for external gain-setting resistors and simplifying PCB layout. Key features include a -2V to +42V common-mode input range that survives load-dump transients in automotive and industrial systems, a fixed gain that improves noise immunity versus discrete op-amp solutions, and a 950 kHz gain-bandwidth product that supports fast transient response for current-mode control loops. The device also delivers 1.8 V/us slew rate, low offset, and integrated EMI filtering. The TSOT-23-6 package offers a compact 2.9 mm x 1.6 mm footprint with thermal performance suitable for industrial temperature ranges (-40C to +125C). The LMP8640MK-H/NOPB uses a precision chopper-stabilized input stage and thin-film resistor network to achieve low offset and high common-mode rejection ratio (CMRR). Its high PSRR ensures accurate current measurement even when the supply rail is noisy, which is critical in switched-mode power supply (SMPS) and motor-drive applications where large dv/dt events couple into the measurement node. Typical applications include high-side current sensing in telecom brick modules, battery-pack current monitoring in e-mobility and UPS systems, motor phase-current sensing in industrial drives, and precision load monitoring in solar inverters. The wide common-mode range also suits 48V telecom rails and 24V industrial automation backplanes. When designing with the LMP8640MK-H/NOPB, select a low-inductance Kelvin-connected sense resistor to avoid errors from PCB trace resistance, and place a 0.1 uF supply bypass capacitor as close to the IC as possible. The internal fixed gain eliminates gain-error calculations but the designer must still budget for sense-resistor tolerance and thermal drift.

According to the TI product page, the device generates an output voltage proportional to the cell current, making it a drop-in read sensor analog subsystem for portable gas detection. An analog front-end (AFE) for electrochemical sensors is a mixed-signal IC that combines a potentiostat (a controlled-voltage/current bias circuit for the sensor working electrode), a transimpedance amplifier (TIA) that converts the sensor's picoampere-level current into a usable voltage, and a digital interface for microcontroller configuration. The LMP91000 sits inside the broader sensor signal chain hierarchy: electrochemical sensor -> AFE/potentiostat -> ADC -> microcontroller. Its programmability enables it to support multiple electrochemical sensors including 3-lead toxic gas sensors and 2-lead galvanic cells. Key features of the LMP91000SD/NOPB include a fully programmable transimpedance amplifier (TIA) gain, programmable bias voltage for the working electrode, programmable load resistor for the reference electrode, and an integrated temperature sensor to compensate for sensor temperature drift. The device also integrates a configurable I2C-compatible serial interface. Its low quiescent current makes it suitable for battery-powered portable gas detectors, and its small 4 mm x 4 mm WSON-14 footprint enables dense PCB layouts in wearable multi-gas sensor modules. Technically, the LMP91000 implements a true potentiostat topology using an op-amp-based control loop with MOSFET output stages, allowing the working electrode potential to be held precisely at the programmed bias voltage while sourcing or sinking the cell current. The integrated 8-bit DAC sets the bias voltage in 1 mV-typical steps, and the TIA gain is programmed through internal feedback resistor selection, giving the designer flexibility to match sensors with different current ranges (nA-level toxic gas sensors to mA-level bio-sensors). Typical applications include portable toxic gas detectors (CO, H2S, NO2), industrial safety monitors, breath analyzers, blood glucose meters, and environmental air-quality monitors. In a portable gas detector, the LMP91000 is placed between the 3-lead electrochemical sensor and a low-power MCU with an integrated ADC; the AFE handles biasing and current-to-voltage conversion while the MCU samples the voltage and applies temperature compensation. When designing with the LMP91000, ensure that the VDD decoupling capacitors are placed as close as possible to the analog and digital supply pins, and that the working, counter, and reference electrode traces are guarded to prevent leakage. The I2C SDA/SCL lines require pull-up resistors to VDD; consult the manufacturer's datasheet for the recommended pull-up value based on bus capacitance and clock speed.

LMV761MF/NOPB

LMV761MF/NOPB - 120ns Precision Comparator | Texas Instruments

The Texas Instruments LMV761MF/NOPB is a single, low-voltage precision comparator with a 120 ns response time, push-pull output, and shutdown capability. It operates from a 2.7 V to 5 V supply and is packaged in a compact 6-pin SOT-23 package. The device is intended for precision signal conditioning, threshold detection, and low-noise analog systems where fast decision-making and low supply current are important. A comparator is an analog integrated circuit that compares two input voltages and changes its output state when the differential input crosses a defined threshold. Unlike an operational amplifier, a comparator is optimized for saturated digital-style output states rather than linear amplification. The LMV761 belongs to the broader semiconductor hierarchy of analog ICs, comparator circuits, and low-voltage precision signal-conditioning components. The LMV761MF/NOPB provides a single comparator channel with rail-to-rail input capability, push-pull output, and a shutdown pin. Its 120 ns propagation delay supports fast decision paths, while its low supply current makes it suitable for portable and low-power equipment. The push-pull output avoids the external pull-up resistor normally required by open-collector comparators, simplifying PCB layout and reducing system component count. This comparator is particularly useful when a system must convert an analog measurement into a logic-level decision without adding substantial propagation delay. Its 2.7 V minimum supply voltage supports low-voltage digital and embedded systems, while operation up to 5 V provides compatibility with conventional low-voltage rails. The SOT-23-6 package supports compact placement, although designers should account for the small thermal footprint and exposed pad limitations of the package family. Typical applications include sensor threshold detection, battery and power-supply monitoring, signal crossing detection, window-comparison circuits, industrial control logic, portable instrumentation, and low-voltage embedded systems. The shutdown function can reduce supply current when the comparator is not needed, helping conserve power in always-on equipment. For reliable operation, connect the supply and ground pins according to the manufacturer datasheet, place bypass capacitance close to the device, and treat unused input pins carefully. Input common-mode range, output drive capability, and shutdown logic should be verified against the system requirements before layout release. This page summarizes verified manufacturer and distributor information alongside practical selection guidance, drop-in alternatives, and design considerations not consolidated in a single source.

LMV761MFX/NOPB

LMV761MFX/NOPB - 120ns Precision Comparator w/ Shutdown | TI | SOT-23-6

The Texas Instruments LMV761MFX/NOPB is a single-channel, 120-ns, low-voltage precision comparator with shutdown and a push-pull output stage, housed in a 6-pin SOT-23 (DBV) package. It operates from a 2.7 V to 5 V single supply, draws a typical quiescent current well below 1 mA in active mode, and integrates a SHDN pin that drops supply current to a sub-microampere level when pulled low. The part is specified over the -40C to +125C industrial temperature range and is lead-free / RoHS compliant (NOPB suffix). A comparator is a high-gain differential amplifier whose output swings fully high or fully low depending on which of its two inputs is more positive. Precision comparators such as the LMV761 are distinguished from general-purpose comparators by very low input offset voltage, low input bias current, and tight propagation delay, making them the reference building block for threshold detection, zero-crossing detection, and analog signal conditioning. The LMV761 belongs to the linear / comparator IC category, sits in the signal-chain hierarchy between analog front-ends and digital logic, and is widely used in battery-powered and space-constrained designs. Key features of the LMV761MFX/NOPB include a 120 ns typical propagation delay, push-pull CMOS output (no pull-up resistor required), rail-to-rail input common-mode range, an active-low shutdown pin for power management, internal hysteresis for clean switching on slow signals, and ESD protection on the pins. The push-pull topology drives CMOS/TTL loads directly with symmetric rise/fall times, which is critical when the comparator output feeds a high-impedance logic input or a microcontroller interrupt. Architecturally, the LMV761 uses a bipolar-CMOS input stage that yields low input bias current combined with low offset, followed by a fast latch and CMOS output drivers. The shutdown circuit is implemented as a gated bias path that collapses the input stage current when SHDN is low, while preserving the output in a defined high-impedance state so downstream circuitry can hold the last logic level. Typical applications include battery management (over-voltage / under-voltage detection), threshold detectors in industrial sensor modules, line drivers and zero-crossing detectors for power-line monitoring, alarm and security subsystems, and general signal conditioning ahead of an MCU ADC. Designers favor it for any 3.3 V or 5 V system that needs a fast, low-power, board-space-saving comparator. When designing with this part, place a 0.1 uF bypass capacitor within a few millimeters of VCC, keep input trace lengths short to minimize parasitic feedback that causes oscillation, and ensure the SHDN pin (when unused) is tied high through a resistor, never left floating. The push-pull output cannot be wire-ORed with another comparator output; if that topology is required, select an open-drain variant instead.

LMV841MGX/NOPB

LMV841MGX/NOPB - 4.5MHz RRIO CMOS Op-Amp, SC-70-5 | TI

The Texas Instruments LMV841MGX/NOPB is a single-channel CMOS input, rail-to-rail input and output (RRIO), low-power operational amplifier that operates over a wide 2.7 V to 12 V supply range. The device is housed in a space-saving 5-pin SOT-SC70 (DCK) package and offers 4.5 MHz unity-gain bandwidth, low offset voltage, and a CMOS input stage. According to the manufacturer datasheet, the LMV84x family is optimized for high-impedance sensor interfaces and battery-powered applications. A CMOS-input op-amp (operational amplifier) is a linear amplifier whose input stage is built using CMOS transistors rather than bipolar junction transistors. CMOS inputs provide extremely high input impedance (very low bias current), making them ideal for interfacing with high-impedance sensors such as photodiodes, electrochemical cells, and piezoelectric transducers. Rail-to-rail input and output (RRIO) capability allows the input common-mode signal and the output swing to reach within millivolts of both supply rails, maximizing dynamic range when operating from low-voltage supplies. These characteristics position the LMV841 within the broader hierarchy of operational amplifier -> amplifier IC -> analog signal chain -> integrated circuit. Key features include a 4.5 MHz gain-bandwidth product, low input bias current due to the CMOS input stage, rail-to-rail input and output swing, low supply current consumption for battery operation, and operation from 2.7 V to 12 V single supply. The CMOS input stage virtually eliminates input bias current errors that would otherwise limit high-impedance sensor designs, while the RRIO capability preserves dynamic range in low-voltage single-supply systems. The 5-pin SC-70 package measures only 2.0 mm x 1.25 mm, enabling high-density analog front-end designs. Typical applications include battery-powered instrumentation, photodiode transimpedance amplifiers, handheld medical devices, sensor signal conditioning, active filters, and portable audio signal chains. The wide supply range allows direct interfacing to lithium-ion cells (3.6 V nominal, 4.2 V peak) as well as 9 V industrial rails without level shifting. When designing with the LMV841, place a 0.1 uF decoupling capacitor within 5 mm of the supply pin to minimize noise coupling. Avoid placing large resistive loads directly at the output when operating near the rails, as the output drive capability degrades within approximately 50 mV of either rail under heavy loading. This page consolidates distributor stock and pricing data, drop-in alternative part numbers in the same SC-70-5 footprint, and practical SC-70 PCB layout guidance that augments the manufacturer datasheet for accelerated component selection.

LMV932MMX/NOPB

LMV932MMX/NOPB - Dual 1.8V RRIO Op Amp 1.5MHz | TI

The Texas Instruments LMV932MMX/NOPB is a dual low-voltage, low-power operational amplifier from the LMV93x-N family, operating from a 1.8V to 5.5V supply with rail-to-rail input and output (RRIO) performance in a space-saving 8-pin VSSOP package. It provides 1.5MHz gain-bandwidth and can source up to 5mA of output current, making it well suited to battery-powered and portable signal conditioning. An operational amplifier (op amp) is a high-gain voltage amplifier with differential inputs and a single-ended output, the fundamental building block of analog signal chains. Within the power-management hierarchy of a system, general-purpose op amps such as this one sit between sensors and ADCs, performing amplification, filtering, buffering, and level shifting. The LMV93x-N family spans a single (LMV931-N), dual (LMV932-N), and quad (LMV934-N) to cover channel-count scaling. Key features include guaranteed operation down to 1.8V for single-cell Li-Ion or two-cell alkaline end-of-life conditions, rail-to-rail input common-mode that extends to both supply rails, and rail-to-rail output swing that maximizes dynamic range at low supply voltages. The NOPB suffix confirms lead-free, RoHS-compliant packaging. Temperature range is -40C to +125C, and the MMX suffix denotes the VSSOP-8 (DGK) surface-mount package suited to area-constrained PCBs. The rail-to-rail input stage typically uses complementary PMOS/NMOS differential pairs to avoid common-mode crossover distortion near the rails, allowing sensor signals at or near ground or VCC to be processed accurately. The output stage swings within millivolts of the rails under light load, maximizing ADC input utilization at 1.8V operation. Typical applications include mobile phone and tablet audio or sensor front ends, battery-powered instrumentation, active filters in portable medical devices, and low-voltage ADC driver stages. The compact VSSOP footprint makes the part a good fit for dense multi-channel boards. Design consideration: at 1.8V supply, output current capability and headroom are limited; keep load impedances above several kilohms and verify bandwidth requirements, since 1.5MHz gain-bandwidth means closed-loop gains of 10 or more restrict usable signal bandwidth to well under 150kHz.

LMX2325TMX-G

LMX2325TMX-G - 2.5GHz PLL Frequency Synthesizer | Rochester

The Rochester Electronics LMX2325TMX-G is a PLL (phase-locked loop) frequency synthesizer IC with a maximum operating frequency of 2.5 GHz, housed in a 20-pin TSSOP (TMX) surface-mount package. It accepts CMOS/TTL inputs and produces CMOS outputs, integrating a single PLL circuit with prescaler logic intended for RF and wireless local-oscillator generation. The device is supplied on Tape-and-Reel and is currently offered through authorized distributor inventory as of 2026-10-08. A PLL frequency synthesizer is a closed-loop feedback circuit that locks a voltage-controlled oscillator (VCO) to a stable, low-frequency reference, multiplying that reference up to a precisely programmable frequency. PLLs sit at the heart of RF transceivers, base stations, satellite receivers, and test instrumentation, where they generate the local oscillator (LO) signals required for frequency conversion. Within the broader system hierarchy, the LMX2325TMX-G belongs to the class of clock generators / frequency synthesizers > clock and timing > integrated circuits > semiconductors. Key features include a maximum synthesized frequency of 2.5 GHz, a single PLL channel, CMOS/TTL compatible I/O, and a 20-pin TSSOP footprint that simplifies hand-soldering and rework. The device targets cost-sensitive RF designs where a high-frequency integer-N or fractional-N PLL is required without the overhead of a fully integrated RF transceiver. Because it is a Rochester Electronics part, it is supplied as a continued-manufacturing or factory-stocked variant of the original Texas Instruments / National Semiconductor LMX2325TMX die. Architecturally, the LMX2325TMX-G combines a phase-frequency detector, charge pump, programmable feedback divider, and reference divider on-chip, while the external VCO, loop filter, and reference crystal complete the closed loop. Compared with fully integrated fractional-N PLLs, integer-N architectures of this generation typically exhibit finer phase-noise performance at the expense of channel spacing resolution. Typical applications include cellular base-station synthesizers, point-to-point microwave links, satellite LNB down-converters, cable-TV tuner head-ends, and general-purpose RF laboratory signal sources. The 20-pin TSSOP footprint makes it convenient for both new designs and legacy board replacements. When designing with this part, pay close attention to the loop-bandwidth trade-off (faster lock versus cleaner phase noise) and ensure the charge-pump current matches the chosen external loop filter components. Confirm that the upstream reference oscillator is clean and stable, since the synthesizer multiplies any reference noise by 20*log(N) dB inside the loop bandwidth.
