Demonstration circuit 2290A features the LTC2387 family. With up to 15Msps, these differential input, single channel, 18-/16-Bit, serial, high speed successive approximation register (SAR) ADCs are available in a 32-Pin QFN package. The LTC2387 family has an internal 20ppm/°C reference and a serial LVDS interface. The demo manual refers to the LTC2387 but applies to all members of the family, the only difference being the sample rate and the number of bits. The DC2290A demonstrates the AC performance of the LTC2387 in conjunction with the DC718 data collection board. Differential amplifier demo boards are available separately that provide amplification of low level differential signals if required. Alternatively, by connecting the DC2290A into a customer application the performance of the LTC2387 can be evaluated directly in that circuit.

The LT3011 is a high voltage, micropower, low dropout linear regulator. The device is capable of supplying 50mA of output current with a dropout voltage of 300mV. Designed for use in battery-powered high voltage systems, the low quiescent current (46?A operating and 1?A in shutdown) is well controlled in dropout, making the LT3011 an ideal choice.The LT3011 includes a PWRGD flag to indicate output regulation. The delay between regulated output level and flag indication is programmable with a single capacitor. The LT3011 also has the ability to operate with very small output capacitors; it is stable with only 1?F on the output. Small ceramic capacitors can be used without the addition of any series resistance (ESR) as is common with other regulators. Internal protection circuitry includes reverse battery protection, current limiting, thermal limiting, and reverse current protection.The LT3011 features an adjustable output with a 1.24V reference voltage. The device is available in the thermally enhanced 12-lead MSOP and the low profile (0.75mm) 10-pin (3mm ? 3mm) DFN package, both providing excellent thermal characteristics.Applications Low Current High Voltage Regulators Regulator for Battery-Powered Systems Telecom Applications Automotive Applications

The LT3029 is a dual, micropower, low noise, low dropout linear regulator. The device operates either with a common input supply or independent input supplies for each channel, over an input voltage range of 1.8V to 20V. Each output supplies up to 500mA of output current with a typical dropout voltage of 300mV. Quiescent current is well controlled in dropout. With an external 10nF bypass capacitor, output noise is only 20?VRMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 55?A quiescent current per channel makes it an ideal choice. In shutdown, quiescent current drops to less than 1?A. Shutdown control is independent for each channel, allowing for flexible power management.The LT3029 optimizes stability and transient response with low ESR ceramic output capacitors, requiring a minimum of only 3.3?F. The regulator does not require the addition of ESR, as is common with other regulators.Internal circuitry provides reverse-battery protection, reverse-current protection, current limiting with foldback and thermal shutdown. The device is available as an adjustable output voltage device with a 1.215V reference voltage. The LT3029 is offered in the thermally enhanced 16-lead MSOP and 16-lead, low profile (4mm ? 3mm ? 0.75mm) DFN packages.Applications General Purpose Linear Regulator Battery-Powered Systems Microprocessor Core/Logic Supplies Post Regulator for Switching Supplies Tracking/Sequencing Power Supplies
