Multiplying digital-to-analog converters (MDACs) produce a (current) output signal that’s a product of the given reference voltage and the code (i.e., a string of 0s and 1s) flowing through it. All data converters require a voltage reference (VREF) and a typical, standard DAC needs a very stable fixed reference voltage in order to operate properly. […]

3 GHz to 20 GHz double balanced mixer performs as up- or downconverter
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC5553, a double balanced mixer providing best-in-class matched bandwidth capability from 3GHz to 20GHz. The mixer can be used either as an up- or downconverter. In addition, the LTC5553 delivers outstanding linearity of 23.9dBm IIP3 at 14GHz, and 21.5dBm at 17GHz. The device integrates […]
Basics of bandpass filters
Filters will allow some signals to pass through while blocking others. A bandpass (a.k.a. band-pass) filter allows signals of a certain frequency range (“a band of frequencies”) to pass through the filter as-is. (This range of accepted frequencies is called the passband. The size or range of the passband is called the bandwidth.) With a […]
50 Mbps RS-485 transceivers with failsafe for common real-world faults
Analog Devices, Inc. today announced the availability of two 50 Mbps RS-485/RS-422 transceivers for use in harsh environments including industrial automation, motor control, military and avionics. The ADM3065E and ADM3066E transceivers combine IEC61000-4-2 Level 4 electrostatic discharge (ESD) protection, high-speed data communication, support of 1.8 VIO logic (ADM3066E), and an industrial temperature range all in […]
Diff amp delivers 15 dB gain to 1.4 GHz
Analog Devices, Inc. announces the LTC6432-15, a wideband fully differential amplifier with 15dB gain, offering linearity of up to +50.3dBm OIP3 (output third-order intercept), very high OP1dB (output 1dB compression point) of +22.7dBm, and 3.2dB noise figure at 150MHz. In addition to its outstanding signal-to-noise at high frequencies, it maintains its dynamic range performance even […]
