The ADM1266 Super Sequencer? is a configurable supervisory/sequencing device that offers a single-chip solution for supply monitoring and sequencing in systems with up to 17 supplies.?For systems with more supplies (up to 257), the operation of up?to 16 ADM1266 devices can be synchronized through a proprietary?2-wire interface (interdevice bus). The sequencing engine (SE) monitors the supply fault detectors?(SFDs), programmable driver input/outputs (PDIOs), general-purpose?inputs/outputs (GPIOs), and timers, and controls the?PDIOs and GPIOs to sequence the supplies up and down as?required. The logical core of the device is an ARM? Cortex-M3?microcontroller. The firmware is supplied by Analog Devices,?Inc., and all configuration is performed through an intuitive?graphic user interface (GUI). Additionally, the ADM1266 integrates an analog-to-digital?converter (ADC) and voltage output digital-to-analog converters?(DACs) that can be used to adjust either the feedback node or?reference of a dc-to-dc converter to implement a closed-loop,?autonomous, margining system.A block of nonvolatile EEPROM is available to record voltage,?time, and fault information when instructed to by the sequencing?engine configuration.APPLICATIONS Communications infrastructure Industrial test and measurement

Using anadvanced proprietary architecture, it provides high powersupply rejection and ultralow noise, achieving excellent line andload transient response with only a 10 ?F ceramic output capacitor.There are 16 standard output voltages for the ADM7154. Thefollowing voltages are available in stock: 1.2 V, 1.8 V, 2.5 V, 2.8 V,3.0 V, and 3.3 V. Additional voltages are available by specialorder: 1.3 V, 1.5 V, 1.6 V, 2.0 V, 2.2 V, 2.6 V, 2.7 V, 2.9 V, 3.1 V,and 3.2 V.The ADM7154 regulator typical output noise is 0.9 ?V rms from100 Hz to 100 kHz for fixed output voltage options and1.5 nV/?Hz for noise spectral density from 10 kHz to 1 MHz. The ADM7154 is available in 8-lead, 3 mm ? 3 mm LFCSP and8-lead SOIC packages, making it not only a very compactsolution, but also providing excellent thermal performance forapplications requiring up to 600 mA of load current in a small,low profile footprint.Applications Regulation to noise sensitive applications: PLLs, VCOs, and PLLs with integrated VCOs Communications and infrastructure Backhaul and microwave links

The ADM7160 is an ultralow noise, low dropout linear regulator that operates from 2.2 V to 5.5 V and provides up to 200 mA of output current. The low 150 mV dropout voltage at 200 mA load improves efficiency and allows operation over a wide input voltage range.Using an innovative circuit topology, the ADM7160 achieves ultralow noise performance without the need for a bypass capacitor, making it ideal for noise-sensitive analog front end and RF applications. The ADM7160 also achieves ultralow noise performance without compromising PSRR or transient line and load performance.Current-limit and thermal overload protection circuits prevent damage under adverse conditions. The ADM7160 also includes an internal pull-down resistor on the EN input.The ADM7160 is specifically designed for stable operation with tiny 1 ?F, ?30% ceramic input and output capacitors to meet the requirements of high performance, space constrained applications.The ADM7160 is available in tiny 5-lead TSOT and 6-lead LFCSP packages with 16 fixed output voltage options, ranging from 1.1 V to 3.3 V. The LFCSP offers a very compact solution that provides excellent thermal performance for applications that require up to 200 mA of output current in a small, low profile footprint.Applications ADC/DAC power supplies RF, VCO, and PLL power supplies Post dc-to-dc regulation

The ADM8611/ADM8612/ADM8613/ADM8614/ADM8615?are voltage supervisory circuits that monitor power supply voltage levels and code execution integrity in microprocessor-based systems. Apart from providing power-on reset signals, an on-chip watchdog timer can reset the microprocessor if it fails to strobe within a preset timeout period. A reset signal can also be asserted by an external push-button through a manual reset input.The ultralow power consumption of these devices makes them suitable for power efficiency sensitive systems, such as battery-powered portable devices and energy meters.The features of each member of the device family are shown in Table 9 in the data sheet. Each device subdivides into submodels with differences in factory preset voltage monitoring threshold options. In the range of 2 V to 4.63 V, 10 options are available for the ADM8611. In the range of 2.32 V to 4.63 V, five options are available for both the ADM8613 and ADM8614. A separate supply input allows the ADM8612 and ADM8615 to monitor 20 different low voltage levels from 0.5 V to 1.9 V. Not all device options are available as standard models.The ADM8611, ADM8612, ADM8613, and ADM8615 can reset on demand through the manual reset input. The watchdog function on the ADM8613, ADM8614, and ADM8615 monitors the heartbeat of the microprocessor through the WDI pin. The ADM8613 and ADM8614 have a watchdog disable input, which allows the user to disable the watchdog function, if required. The ADM8614 also has a watchdog timeout extension input, allowing the watchdog timeout to be extended from 1.6 sec to 100 sec.The ADM8611/ADM8612/ADM8613/ADM8614/ADM8615 are available in a 6-ball, 1.46 mm ? 0.96 mm WLCSP.
