REF02AJ/883C

Analog Devices Inc.
The REF01 / REF02 / REF03 series of precision voltage references provide a stable 10.0 V, 5.0 V, or 2.5 V output with minimal change in response to variations in supply voltage, ambient temperature or load conditions. The devices are available in 8-lead SOIC, PDIP, CERDIP, and TO-99 packages, as well as 20-terminal LCC packages (883 only), furthering the usability of the devices in both standard and high stress applications.With an external buffer and a simple resistor network, the TEMP terminal can be used for temperature sensing and approximation. A TRIM terminal is also provided on the device for fine adjustment of the output voltage.The small footprint, wide supply range, and application versatility make the REF0x series of references ideal for general-purpose and space-constrained applications.Newer designs should use the ADR01 / ADR02 / ADR03 / ADR06 series of references, which offer higher accuracy and temperature stability over a wider operating temperature range, while maintaining full pin-for-pin compatibility with the REF01 / REF02 / REF03 series.

REF192GRUZ

Analog Devices Inc.
The REF19x series precision band gap voltage references use a patented temperature drift curvature correction circuit and laser trimming of highly stable, thin-film resistors to achieve a very low temperature coefficient and high initial accuracy.The REF19x series is made up of micropower, low dropout voltage (LDV) devices, providing stable output voltage from supplies as low as 100 mV above the output voltage and consuming less than 45 μA of supply current. In sleep mode, which is enabled by applying a low TTL or CMOS level to the SLEEP pin, the output is turned off, and supply current is further reduced to less than 15 µA.The REF19x series references are specified over the extended industrial temperature range (−40°C to +85°C), with typical performance specifications over −40°C to +125°C for applications such as automotive.All electrical grades are available in an 8-lead SOIC_N package; the PDIP and TSSOP packages are available only in the lowest electrical grade. Products are also available in die form.APPLICATIONS Portable instruments ADCs and DACs Smart sensors Solar-powered applications Loop current-powered instruments

DC1053A-H

Analog Devices Inc.
The LTC3526/LTC3526B are synchronous, fixed frequency step-up DC/DC converters with output disconnect. Synchronous rectification enables high efficiency in the low profile 2mm × 2mm DFN package. Battery life in single AA/AAA powered products is extended further with an 850mV start-up voltage and operation down to 500mV once started.A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The current mode PWM design is internally compensated, reducing external parts count. The LTC3526 features automatic Burst Mode operation at light load conditions, while the LTC3526B features continuous switching at light loads. Anti-ringing control circuitry also reduces EMI concerns by damping the inductor in discontinuous mode. Additional features include a low shutdown current of under 1μA and thermal shutdown.The LTC3526/LTC3526B are housed in a 2mm × 2mm × 0.75mm DFN package.For new designs, we recommend the LTC3526L/LTC3526LB.   Startup Voltage Frequency Burst Mode Notes LTC3526 1V 1MHz Yes Not Recommended For New Designs LTC3526B 1V 1MHz No Not Recommended For New Designs LTC3526-2 1V 2MHz Yes Not Recommended For New Designs LTC3526B-2 1V 2MHz No Not Recommended For New Designs LTC3526L 0.85V 1MHz Yes   LTC3526LB 0.85V 1MHz No   LTC3526L-2 0.85V 2MHz Yes   LTC3526LB-2 0.85V 2MHz No   APPLICATIONS Medical Instruments Flash-Based MP3 Players Noise Canceling Headphones Wireless Mice Bluetooth Headsets

Analog Devices Inc.
The LTC4263 is an autonomous single-channel PSE controller for use in IEEE 802.3af compliant Power over Ethernet systems. It includes an on-board power MOSFET, internal inrush, current limit, and short-circuit control, IEEE 802.3af compliant PD detection and classification circuitry, and selectable AC or DC disconnect sensing. On-board control algorithms provide complete IEEE 802.3af compliant operation without the need of a microcontroller. The LTC4263 simplifies PSE implementation, needing only a single 48V supply and a small number of passive support components.Programmable on-board power management circuitry permits multiple LTC4263s to allocate and share power in multi-port systems, allowing maximum utilization of the 48V power supply—all without the intervention of a host processor. The port current limit can be configured to automatically adjust to the detected PD class. Detection back-off timing is configurable for either Endpoint or Midspan operation. Built-in foldback and thermal protection provide comprehensive fault protection.An LED pin indicates the state of the port controlled by the LTC4263. When run from a single 48V supply, the LED pin can operate as a simple switching current source to reduce power dissipation in the LED drive circuitry.The LTC4263 is available in 14-pin 4mm × 3mm DFN and 14-pin SO packages.Applications IEEE 802.3af Compliant Endpoint/Midspan PSEs Single-Port or Multi-Port Power Injectors Power Forwarders Low-Port Count PSEs Environment B PSEs Standalone PSEs
