Glenrothes, Scotland — TT electronics BI Technologies SMT Division has developed a series of miniature surface-mount resistor ladder networks for analog to digital (A/D) and digital to analog (D/A) ...

With modern microcontrollers, the process of interfacing with the analogue world is easy. Simply enable the on-board DAC or ADC, and talk to the world. If you’ve ever done this with a slightly older ...

To provide a cost-effective means of implementing analogue-to-digital and digital-to-analogue signal conversions, TT electronics BI Technologies has released a series of 8-bit and 10-bit R2R resistor ...

Claimed to be ideal for D/A and A/D conversions, the R/2R thin-film resistor ladder networks are available in values from 10 ohms to 1 Megaohm. The networks have a TCR of ±100 ppm/°C and an absolute ...

Working on high voltage circuits can be dangerous. Capacitors can maintain high voltage in a system for a considerable time after power is removed. Running an LED off a high voltage source typically ...

FiiO’s product release schedule has gone properly bonkers in 2025. At roughly one new announcement per week, keeping up with its catalogue has become a full-time job – and that’s before we’ve even ...

The R-2R ladder, a well known resistor topology, is often used to implement a current or voltage 6-dB step attenuator. By appropriately scaling the resistor values ...

The FiiO DM15 R2R is a portable and desktop CD player that doubles as a DAC. It also adds Bluetooth streaming for headphones and wireless speakers. Available now, it's reassuringly affordable at £249 ...

$319 hi-res desktop DAC/AMP with balanced/single-ended outputs, Bluetooth 5.4, USB, optical, coax, and I²S connectivity. After a short listening session with the HiFiMAN HE1000 Unveiled, eCoustics ...

[jefffolly] published some straight forward plans for a passive volume control. It uses a resistive ladder built across the contacts of 12W rotary switches. Each resistor provides a 5dB difference, ...
