Micropower 12-Bit ADCs Shrink Board Space вЂ“ Design Note 116
Kevin R. Hoskins Many portable and battery-powered systems require
internal analog-to-digital conversion. Some, such as
pen-based computers, have ADCs at their very cores
digitizing the pen screen. Other systems use ADCs more
peripherally to monitor voltages or other parameters
inside the equipment. Regardless of the use, it has been
difп¬Ѓcult to obtain small ADCs at power levels and prices
that are low enough. The LTC1286/LTC1298 meet these
low power dissipation and package size needs.
Micropower and 12-Bits in an SO-8 Package
The LTC1286/LTC1298 are the latest members of the
growing family of SO-8 packaged parts (TableВ 1).
As the п¬Ѓrst of their kind in SO-8 packages, these are
improvements to the 8-bit micropower LTC1096/
LTC1098 ADCs. The LTC1286/LTC1298 use a successive approximation register (SAR) architecture. Both
converters contain sample-and-holds and serial data

Applications of a Rail-to-Rail Amplifier вЂ“ Design Note 89
William Jett and Sean Gold
The LTВ®1366 is Linear TechnologyвЂ™s п¬Ѓrst bipolar dual
operational ampliп¬Ѓer to combine rail-to-rail input and
output operation with precision VOS speciп¬Ѓcations. The
LT1366 maintains precision speciп¬Ѓcations over a wide
range of operating conditions. The device will operate
with supply voltages as low as 1.8V and is fully speciп¬Ѓed for 3V, 5V, and В±15V operation. Offset voltage is
typically 200ОјV when operating from a single 5V supply. Open-loop gain, AVOL, is 2 million driving a 2kО©
load. Supply current is typically 375ОјA per ampliп¬Ѓer.
The combination of precision speciп¬Ѓcations and rail-torail operation makes the LT1366 a versatile ampliп¬Ѓer,
suitable for signal processing tasks that demand the
widest possible common-mode range.
Precision Low Dropout Regulator
Microprocessors and complex digital circuits frequently
specify tight control of power supply characteristics.
The circuit shown in Figure 1 provides a precise 3.6V,
1A output from a minimum 3.8V input voltage. The
circuitвЂ™s nominal operating voltage is 4.75V В±5%. The
voltage reference and resistor ratios determine output
voltage accuracy, while the LT1366вЂ™s high gain enforces
0.2% line and 0.2% load regulation. Quiescent current
is about 1mA and does not change appreciably with supply or load. All components are available in surface …
