LM4562, AD8250

ACCEL INDUSTRIAL LIMITED

Thousands of tiny transistors, diodes, resistors and capacitors are fabricated on a semiconductor wafer forms integrated circuit.there are two types of ic, CMOS ic and digital ic. MOSFETs come in four different types. They may be enhancement or depletion mode, and they may be n-channel or p-channel.There are also logic-level MOSFETs and normal MOSFETs.

Part number: LM4562

Category:
Analog & Mixed-Signal Processing
-> Amplifiers
-> Audio/Power Amplifiers

Description:
The LM4562 is part of the ultra-low distortion, low noise, high slew rate operational amplifier series optimized and fully specified for high performance, high fidelity applications. Combining advanced leading-edge process technology with state-of-the-art circuit design, the LM4562 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. The LM4562 combines extremely low voltage noise density (2.7nV/SqrtHz#) with vanishingly low THD+N (0.00003%) to easily satisfy the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LM4562 has a high slew rate of ±20V/μs and an output current capability of ±26mA. Further, dynamic range is maximized by an output stage that drives 2k loads to within 1V of either power supply voltage and to within 1.4V when driving 600 loads. The LM4562's outstanding CMRR (120dB), PSRR (120dB), and VOS (0.1mV) give the amplifier excellent operational amplifier DC performance. The LM4562 has a wide supply range of ±2.5V to ±17V. Over this supply range the LM4562's input circuitry maintains excellent common-mode and power supply rejection, as well as maintaining its low input bias current. The LM4562 is unity gain stable. This Audio Operational Amplifier achieves outstanding AC performance while driving complex loads with values as high as 100pF. The LM4562 is available in 8-lead narrow body SOIC, 8-lead Plastic DIP, and 8-lead Metal Can TO-99. Demonstration boards are available for each package.

Part number: AD8250

Category:
Analog & Mixed-Signal Processing
-> Amplifiers
-> Instrumentation Amplifiers

Description:
The AD8250 is a digitally gain programmable instrumentation amplifier that has high G Ω input impedance and low distortion making it suitable for sensor interfacing and driving high sample rate analog to digital converters. It has high bandwidth of 12 MHz, low distortion and settle time of 0.5 μs to 0.01%. Offset drift and gain drift are limited to 1 μV/°C, respectively. In addition to its wide input common voltage range, it boasts a high common-mode rejection of 80 dB at G = 1 from DC to 50 kHz. The combination of precision DC performance coupled with high speed capabilities make the AD8250 an excellent candidate for data acquisition and medical applications. Furthermore, this monolithic solution simplifies design, manufacturing and boosts performance of instrumentation by maintaining tight match of internal resistors and amplifiers.

The AD8250 is available in a 10-lead MSOP package and specified over -40°C to 85°C, making it an excellent solution for applications where size and packing density are important considerations.
