Cadeka's Wide Input Voltage JFET Comparators are a high-speed, wide common mode voltage, JFET input, dual comparators. These Wide Input Voltage JFET Comparators are designed for applications that measure critical timing parameters in which wide common mode input voltages are required. Propagation delays for Cadeka's Wide Input Voltage JFET Comparators are constant for overdrives greater than 200 mV for the SPT9691 and 50mV for the SPT9693. JFET inputs for these Wide Input Voltage JFET Comparators reduce the input bias currents to the nanoamp level, eliminating the need for input drivers and buffers in most applications. Cadeka's Wide Input Voltage JFET Comparators have differential analog inputs and complementary logic outputs compatible with ECL systems.
Cadeka's Dual Ultrafast Voltage Comparators are very high-speed comparators that are pin compatible with, and have improved performance over, Analog Device's AD9687 and Signal Processing Technologies SPT9689, respectively. These Dual Ultrafast Voltage Comparators are designed for use in Automatic Test Equipment (ATE), high speed instrumentation, window comparators, high-speed timing, line receivers and threshold detection applications. Cadeka's Dual Ultrafast Voltage Comparators improvements over other sources include reduced power consumption, reduced propagation delays, and higher input impedance.
Cadeka's COMLINEAR® Standard Definition Video Amplifier is a triple low cost video amplifier capable of driving 2Vpp into 1 (150Ω) or 2 (75Ω) video loads. The COMLINEAR® Standard Definition Video Amplifier features integrated 8MHz, 4th-order low pass filters designed to cleanly pass standard definition video signals while filtering out noise and other unwanted signals, resulting in a crisper, cleaner video signal. Cadeka's COMLINEAR® Standard Definition Video Amplifier offers a fixed gain of 6dB. The COMLINEAR® CLC3800 can be driven by DC-coupled signals and its outputs can drive either AC- or DC-coupled loads.
Cadeka Hybrid Amplifiers are high-speed hybrid amplifiers that are manufactured using Cadeka's internal thin film deposition process. These high performance Hybrid Amplifiers are direct replacements for National/Comlinear hybrid products. Cadeka Hybrid Amplifiers offer a unique combination of speed, dynamic range, low distortion, and drive capability making them ideally suited for many high-end instrumentation, industrial, and military applications. These Hybrid Amplifiers include fast settling, overdrive-protection, low distortion, high speed, high current wideband, linear and differential input/output amplifiers.
Cadeka CDK8307B high-performance, utra-low power octal analog-to-digital converters (ADCs) employ internal reference circuitry, a serial control interface, and serial LVDS output data. Cadeka CDK8307B ultra-low power 12 / 13-bit ADCs feature an integrated PLL that multiplies the input sampling clock by a factor of 12 or 14, according to the LVDS output setting. The multiplied clock is used for data serialization and data output. Data and frame synchronization output clocks are supplied for data capture at the receiver. These Cadeka devices provide 35mW/channel low power dissipation at 40MSPS. CDK8307B ADCs are ideal for use in medical imaging, wireless infrastructure, test and measurement, and instrumentation applications.
Cadeka CDK3404 8-bit triple digital-to-analog converters (DACs) are tailored to fit graphics and video applications where speed is critical. These 8-bit, 180MSPS triple DACs feature CMOS-level inputs that are converted to analog current outputs that can drive 25-37.5Ω loads corresponding to doubly-terminated 50-75Ω loads. The Cadeka CDK3404 provides ±2.5% gain matching and ±0.5% linearity error and offer sync and blank controls. Cadeka CDK3404 DACs are designed for use in a variety of applications, including video signal conversion, multimedia systems, image processing, and PC graphics.
