A/D converter boasts power dissipation of 1.55 W per channel
Analog Devices, Inc. announced a 14-bit, 2.6 GSPS dual A/D converter which enables IF/RF sampling with superior speed and linearity. The AD9689 A/D converter features power dissipation of 1.55 W per channel, half the dissipation of comparable solutions in the market, thus further increasing suitability for many of its targeted design situations. In addition to the […]
Directional bridge/dual RMS RF power detector IC covers 9 kHz to 7 GHz
Analog Devices, Inc. introduced a 9 KHz – 7 GHz directional bridge and dual RMS RF power detector that can simultaneously measure forward and reverse RMS power levels in a signal path along with return loss. The new ADL5920 detector represents a change to conventional approaches by integrating a directional bridge-based coupler that results in an […]
Current feedback amplifiers, Part 2
Part 1 of this FAQ look at the operation of the CFB op amp and compared it to the VFB op amp. Part 2 continues the discussion of these two op amp topologies and their characteristics. Q: How do you choose between VFB versus CFB? A: Today’s CFB and VFB amplifiers have comparable performance, but […]
Current feedback amplifiers, Part 1
Almost every engineer who has to deal with real-world signals, analog sensors, front-end circuitry, filtering, line drivers/receivers, or general amplification is familiar with the basic operational amplifier (op amp) which is the building block of most analog circuity. These op amps generally use voltage feedback (VFB), and have been studied and used extensively. However, there […]

Super-small 3-to-20-GHz mixer supports dc-to-6-GHz IF
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC5552, a double balanced mixer that features best-in-class wideband matching from 3GHz to 20GHz. The mixer can be used as an up- or downconverter. The LTC5552 is especially useful in upconversion applications with its DC capable differential IF port that enables the LO to be […]
Analog switch vs. digital switch ICs
Analog switch integrated chips (ICs), when turned on, will conduct both analog and digital signals from the input pin to the output pin. Digital switches can only accept digital signals and duplicate the logic level on the input pin at the output pin. When the digital switch is turned off, it returns to a default […]
Analog comparators and hysteresis
A standard system requirement is to use the result of a simple “A vs. B” comparison as a basis for decision-making. For example, if the temperature is above a setpoint, turn the heat source off; and if the temperature is below that setpoint, turn the heat source on. Or perhaps there’s an alarm to sound […]
Zero-drift op amp consumes just 1.3 μA
Analog Devices, Inc. announces the LTC2063 zero-drift op amp which draws just 1.3μA typ (2μA max) on a 1.8V supply. This micropower amplifier maintains uncompromised precision: maximum input offset voltage is 5μV at 25°C, maximum drift is 0.06μV/°C from –40°C to 125°C. Maximum input bias current is 15pA at 25°C, and 100pA from –40°C to […]
