The ADP2126 / ADP2127 are high frequency, step-down, dc-to-dc converters optimized for portable applications in which board area and battery life are critical constraints. The fixed 6 MHz operating frequency enables the use of tiny ceramic inductors and capacitors and the regulators use spread spectrum frequency modulation to reduce EMI. Additionally, synchronous rectification improves efficiency and results in fewer external components.At high load currents, the ADP2126 / ADP2127 use a voltage regulating pulse-width modulation (PWM) mode that maintains a constant frequency with excellent stability and transient response. Light load operation is determined by the state of the MODE pin. In forced PWM mode, the converter continues operating in PWM for light loads. Under light load conditions in auto mode, the ADP2126 / ADP2127 automatically enter a power-saving mode, which uses pulse frequency modulation (PFM) to reduce the effective switching frequency, thus ensuring the longest battery life in portable applications.The ADP2126 / ADP2127 are enabled by a 6 MHz to 27 MHz external clock signal applied to the EXTCLK pin. Certain models can also be enabled with a logic high signal. When the external clock is not switching and in a low logic state, the ADP2126 / ADP2127 stop regulating and shut down to draw less than 0.3 μA (typical) from the source.The ADP2126 / ADP2127 have an input voltage range of 2.1 V to 5.5 V, allowing the use of single Li+/Li polymer cell, three-cell alkaline, NiMH cell, and other standard power sources. The ADP2126 / ADP2127 are internally compensated to minimize external components and can source up to 500 mA. Other key features, such as cycle-by-cycle peak current limit, soft start, undervoltage lockout (UVLO), output-to-ground short-circuit protection, and thermal shutdown provide protection for internal and external circuit components.APPLICATIONS Mobile phones Digital still/video cameras Digital audio Portable equipment Camera modules Image stabilization systems

The ADuM6210 / ADuM6211 / ADuM6212 are dual-channel digital isolators with isoPower®, an integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-dc converter provides regulated, isolated power that is adjustable between 3.135 V and 5.25 V. Input supply voltages can range from slightly below the required output to significantly higher. Popular voltage combinations and their associated power levels are shown in Table 2.The ADuM6210 / ADuM6211 / ADuM6212 eliminate the need for a separate, isolated dc-to-dc converter in low power, isolated designs. The iCoupler chip-scale transformer technology is used for isolated logic signals and for the magnetic components of the dc-to-dc converter. The result is a small form factor, total isolationsolution.isoPower uses high frequency switching elements to transfer power through its transformer. Take special care during printed circuit board (PCB) layout to meet emissions standards.

The LTC2983 measures a wide variety of temperature sensors and digitally outputs the result, in ?C or ?F, with 0.1?C accuracy and 0.001?C resolution. The LTC2983 can measure the temperature of virtually all standard (type B, E, J, K, N, S, R, T) or custom thermocouples, automatically compensate for cold junction temperatures and linearize the results. The device can also measure temperature with standard 2-, 3- or 4-wire RTDs, thermistors and diodes. It has 20 reconfigurable analog inputs enabling many sensor connections and configuration options. The LTC2983 includes excitation current sources and fault detection circuitry appropriate for each type of temperature sensor.The LTC2983 allows direct interfacing to ground referenced sensors without the need for level shifters, negative supply voltages, or external amplifiers.

The ADG2128?is an analog cross point switch with an array size of 8 ? 12. The switch array is arranged so that there are eight columns by 12 rows, for a total of 96 switch channels. The array is bidirectional, and the rows and columns can be configured as either inputs or outputs. Each of the 96 switches can be addressed and configured through the I2C compatible interface. Standard, full speed, and high speed (3.4 MHz) I2C interfaces are supported. Any simultaneous switch combination is allowed. An additional feature of the ADG2128 is that switches can be updated simultaneously, using the LDSW command. In addition, a RESET option allows all of the switch channels to be reset/off. At power-on, all switches are in the off condition.

Both Devices use current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response.
