General-purpose DACs address a wide range of applications including
instrumentation, industrial control, and setting voltages and
currents in all manner of analog circuits. In this video, we demonstrate
the 16-/12-bit LTC2668, a 16-channel, voltage output DAC with five
software-programmable (SoftSpan™) or pin-configurable output voltage
ranges up to ±10V. Each output span is independently selectable per
channel, with full 16-bit resolution at all spans. All spans are derived from
an internal 2.5V, 10ppm/°C (max) reference. Additional features include
an internal 16:1 analog multiplexer for calibration or monitoring circuit integrity,
and a toggle function that allows the DAC to quickly toggle between
two DAC codes.
The Serial Peripheral Interface (SPI) has a separate supply pin, allowing a
direct interface to 1.8V FPGAs, 5V microcontrollers, or any logic voltage between.
The demo board is compatible with Linear Technology's Linduino™
microcontroller platform, with C libraries provided to greatly speed up

||Active Clamp Synchronous Forward Controllers
by ARROW - 2014-07-31 13:54 - 4,936 views
The LT3752, LT3752‑1 and LT3753 are active clamp forward controllers
that minimize external component count, solution size and cost. Two of
these controllers, the LT3752 and LT3753, are designed for inputs up
to 100V. The LT3752-1 is designed for applications with input voltages
greater than 100V, suitable for HV car battery and offline isolated power
supplies, industrial, automotive and military systems.
The LT3752, LT3752-1 and LT3753 simplify the design and improve
performance to isolated power supplies with a volt-second clamp architecture
that produces accurate regulation. An integrated flyback controller can be
used to produce a housekeeping supply, simplifying the magnetics. Additional
features include programmable overcurrent protection, adjustable input undervoltage
and overvoltage lockout, programmable turn-on current spike blanking and
programmable delays between various gate signals.
