Demonstration circuit DC1154 is a Telecom non isolated DC/DC converter featuring the LTC3873 constant frequency current mode flyback controller. The DC1154 converts 36V to 72V input voltage to an isolated 3A of output current at 3.3V. The 200kHz constant frequency operation is maintained down to very light load to reduce low frequency noise generated over a wide range of load current. The DC1154 also provides an isolated design by installing the optocoupler and LTC4430 related circuitry. The demonstration circuit can be easily modified to generate different output voltages up to 15V. As output voltage is increased, the maximum output current must be reduced to limit the output power to no more than 10W.

Demonstration circuit 1344A is a low quiescent current step-down DC/DC converter featuring the LTC3834 in a 20-pin TSSOP exposed pad package. The DC1344A is programmed to generate a regulated 3.3V@5A output from a 4.5V to 32V input voltage.

Demonstration circuit 1333A features the LTC2640, a 12-bit SPI DAC. This device establishes a new benchmark for size and integration of 12-bit DACs and onboard reference.

The ADCMP608 is a fast comparator fabricated on XFCB2, an Analog Devices, Inc. proprietary process. This comparator is exceptionally versatile and easy to use. Features include an input range from VEE ? 0.2 V to VCC + 0.2 V, low noise, TTL-/CMOS-compatible output drivers, and shutdown inputs. The device offers 40 ns propagation delays driving a 15 pF load with 10 mV overdrive on 500 ?A typical supply current.A flexible power supply scheme allows the device to operate with a single +2.5 V positive supply and a ?0.2 V to + 2.7 V input signal range up to a +5.5 V positive supply with a ?0.2 V to +5.7 V input signal range.The TTL-/CMOS-compatible output stage is designed to drive up to 15 pF with full rated timing specifications and to degrade in a graceful and linear fashion as additional capacitance is added. The input stage of the comparator offers robust protection against large input overdrive, and the outputs do not phase reverse when the valid input signal range is exceeded.The ADCMP608 is available in a tiny 6-lead SC70 package with a single-ended output and a shutdown pin.APPLICATIONS High speed instrumentation Clock and data signal restoration Logic level shifting or translation High speed line receivers Threshold detection Peak and zero-crossing detectors High speed trigger circuitry Pulse-width modulators Current-/voltage-controlled oscillators

The EVAL-ADXL314Z is a simple evaluation board that allows quick evaluation of the performance of the ADXL314, 3-axis digital accelerometer. The EVAL-ADXL314Z is ideal for evaluation of the ADXL314 in an existing system because the stiffness and the small size of the EVAL-ADXL314Z minimizes the effect of the board on both the system and acceleration measurements. For full details on the ADXL314, see the ADXL314 data sheet, which should be consulted in conjunction with the user guide when using the EVAL-ADXL314Z evaluation board.

Demonstration circuit 1812A (Figure 1) features the LTC2943. The LTC2943 has an operating range of 3.6V to 20V making it perfectly suited for multicell battery applications. A precision analog coulomb counter integrates current measured through a sense resistor between the battery’s positive terminal and the load or charger. The default value assembled on the DC1812A-A is 100mΩ for a maximum current measurement of 500mA. The LTC2943 measures voltage, current and temperature with an internal 14-bit No Latency ΔΣ™ ADC. The measurements are stored in internal registers accessible via the onboard SMBus/I2C interface.
