The LT1970A is a ?500mA power op amp with precise externally controlled current limiting. Separate control voltages program the sourcing and sinking current limit sense thresholds with 1% accuracy. Output current may be boosted by adding external power transistors.The circuit operates with single or split power supplies from 5V to 36V total supply voltage. In normal operation, the input stage supplies and the output stage supplies are connected (VCC to V+ and VEE to V?).

The amplifier is unity-gain stable with a 3.6MHz gain-bandwidth product and slews at 1.6V/?s. The LT1970A can drive capacitive and inductive loads directly.Open-collector status flags signal current limit circuit activation, as well as thermal shutdown of the amplifier. An enable logic input puts the amplifier into a low power, high impedance output state when pulled low. Thermal shutdown and a ?800mA fixed current limit protect the chip under fault conditions.The LT1970A is packaged in a 20-lead TSSOP package with a thermally conductive copper bottom plate to facilitate heat sinking.Applications Automatic Test Equipment Laboratory Power Supplies Motor Drivers Thermoelectric Cooler Driver

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.
