SAE ADCs boast sampling speeds of 10 to 125 MSPS
Texas Instruments expanded its portfolio of high-speed data converters with a broad new family of successive approximation register (SAR) analog-to-digital converters (ADCs) that enable high-precision data acquisition in industrial designs. Featuring best-in-class dynamic range at the lowest power consumption, the ADC3660 family includes eight SAR ADCs in 14-, 16- and 18-bit resolution at sampling speeds […]
Understanding the lock-in amplifier, Part 2: The homodyne solution
The lock-in amplifier allows tiny signals from sensors to be captured with precision despite unavoidable noise limitations and other test and measurement challenges of the signal chain. Part 1 of this article looked at the changes of capturing low-level signals such as from a photodetector despite unavoidable signal-path noise, drift, offsets, and other imperfections. This […]

Small-to-large I/O sockets handle BGA chip testing tasks
New Grypper test sockets handle any BGA devices including large array ASICs and the smallest I/O down to 0.35-mm pitch. The Grypper socket can be designed to any I/O count specific to custom BGA requirements. The Ironwood Grypper G80 LIF socket, part number GR1005-XXXX, allows the testing of an 896-I/O, 31.0×31.0-pitch BGA package. This design […]
Software tool helps designers place antennas in design
Antenova Ltd has created a new software tool to help designers place antennas in a wireless design. The tool displays the optimum position for embedded antennas on the PCB, depending upon the dimensions of the PCB and the specifications of the antennas. It places each individual antenna on the PCB in the best location for […]
Heilind Electronics offers extended series of rugged omnidirectional base station and marine antennas
Heilind Electronics has expanded its antenna portfolio to include CXL Series omnidirectional base station antennas. The antennas are offered in various models to include lightweight, medium-duty, heavy-duty, ATEX-certified, and marine applications.

Input bias current cancellation in bipolar op amps
Bipolar operational amplifiers have an essential input bias current requirement. This bias current has to come from somewhere and can be a nuisance in some types of high impedance circuits such as charge amplifiers and transimpedance amplifiers and can result in offset voltages where input resistances aren’t matched. The example shown below has an input […]
