DC1266A-A: Demo Board for the LTC2453 Ultra-Tiny, Differential, 16-Bit ∆Σ ADC With I2C Interface

Demonstration circuit 1267A is a step-up DC/DC regulator featuring the LTC3125EDCB and is ideally suited for pulsed load applications where the input current needs to be limited. Demonstration circuit 1267A is configured for 500mA maximum input current limit and can handle pulsed load currents of up to 2A, with duty cycles of up to 15%. The input voltage range is 3.3V ±10%.

The LTC1520 is a high speed, precision differential line receiver that can operate at data rates as high as 50Mbps. A unique architecture provides very stable propagation delays and low skew over a wide input common mode, input overdrive and ambient temperature range. Propagation delay is 18ns ?3ns, while typically tPLH/tPHL skew is 500ps and channel-to-channel skew is 400ps.Each receiver translates differential input levels (VID ? 100mV) into valid CMOS and TTL output levels. Its high input resistance (?18k) allows many receivers to be connected to the same driver. The receiver outputs go into a high impedance state when disabled.Protection features include thermal shutdown and a controlled maximum short-circuit current (50mA max) that does not oscillate in and out of short-circuit mode. Input resistance remains ?18k when the device is unpowered or disabled, thus allowing the LTC1520 to be hot swapped into a backplane without loading the data lines.The LTC1520 operates from a single 5V supply and draws 12mA of supply current. The part is available in a 16-lead narrow SO package.Applications High Speed Backplane Interface Line Collision Detector PECL and LVDS Line Receivers Level Translator Ring Oscillator Tapped Delay Line

DC1273A: Demo Board for LT1938 - 25V, 2.2A, 2.8MHz Step-Down Switching Regulator

Demonstration circuit 1294A exercises four adjustable linear regulators in parallel using the LT3080. A small 20 mΩ ballast resistor is required for parallel operation. A short PCB trace can easily serve that purpose. The paralleled devices provide up to 4.4A of output current at 3.3V. Architected as a precision current source and voltage follower, the LT3080 can be used in many applications requiring high current, adjustability to zero output, and no heat sink. The device brings out the collector of the pass transistor to allow low dropout operation when used with multiple supplies. The LT3080's output voltage can be programmed to any level between 0V and 36V; however the demo board has a reduced input voltage range from 3.8V to 25V due to the input capacitor voltage rating.

Demonstration circuit DC1297B features the LTM4612EV, an EN55022 Class B certified synchronous step-down power module. The board accepts an input voltage from 5V to 36V and delivers a jumper programmable output voltage of 3.3V, 5V or 12V. The rated load current is 5A for 3.3V and 5V output voltages, or 3A for a 12V output. Current derating is necessary for certain VIN, VOUT, and thermal conditions.
