Shenzhen Mingjiada Electronics Co., Ltd. — Providing long-term, one-stop supply services for TI's full range of amplifier products, including but not limited to: current sense amplifiers, differential amplifiers, instrumentation amplifiers, and more. Mingjiada Electronics maintains robust and reliable supply channels, rigorously controlling the supply chain to ensure the stability and reliability of supplied products.
1. Current Sense Amplifiers
Current sense amplifiers serve as core components within power management systems, enabling high-precision current monitoring without disrupting the main current path. They provide critical protection functions for battery management systems (BMS), motor drives, and power supply equipment.
Mingjiada supplies models including, but not limited to:
INA2181A4QDGSRQ1: Automotive-grade bidirectional current sense amplifier supporting a wide common-mode voltage range of -16V to +80V. AEC-Q100 certified with error below ±0.5%, specifically designed for electric vehicle control systems.
INA190: Ultra-low power variant (65µA operating current), supporting 0.2V to 5.5V common-mode voltage, suitable for portable device battery monitoring
INA240: Enhanced PWM suppression capability enabling precise motor phase current measurement in high-noise environments
Application scenarios: EV BMS current monitoring, server power supply overload protection, industrial motor drive current feedback
2. Differential Amplifiers
Differential amplifiers maintain signal integrity in complex electromagnetic environments by suppressing common-mode noise, serving as core components in high-speed communications, professional audio-visual equipment, and precision instruments.
Models supplied by Mingjiada include, but are not limited to:
THS4509: Ultra-wideband differential amplifier (2.7GHz gain-bandwidth product), 4900V/µs slew rate, supports high-speed ADC driving, suitable for 5G base station RF units
LMH5401: Low distortion (-100dBc HD3@100MHz), supporting differential outputs up to 8Vpp for medical imaging equipment and test instruments
ADS4122 Companion Amplifier: Differential driver optimised for 14-bit high-speed ADCs, reducing signal settling time
Core Value: Enhances signal-to-noise ratio in high-speed data acquisition systems, addressing signal attenuation during long-distance transmission
3. Instrumentation Amplifiers
Instrumentation amplifiers feature exceptionally high common-mode rejection ratio (CMRR) and low drift characteristics, enabling extraction of faint sensor signals from high-noise backgrounds. They serve as critical preamplifiers for industrial sensor interfaces and medical equipment.
Models supplied by Mingjiada include, but are not limited to:
INA128: Classic precision instrumentation amplifier with CMRR up to 120dB (G=100), input bias current of just 5nA, widely used in pressure sensors and electronic weighing systems
INA333: Ultra-low power zero-drift type (operating current 50µA), quiescent current only 50µA, supports 1.8V low-voltage operation, suitable for portable medical devices
PGA280: Programmable gain instrumentation amplifier with digitally controlled gain range from 0.125 to 128, integrating a 24-bit Σ-Δ ADC
Quality Assurance: Mingjiada Electronics maintains robust and reliable supply channels, rigorously managing the supply chain to ensure product stability and reliability.
Adequate Stock Availability: Mingjiada Electronics holds substantial inventory of TI amplifiers, capable of fulfilling both small-batch sample and large-volume procurement requirements.
