    8-Bit Serial I/O A/D Converters
    FEATURES DESCRIPTION n The LTC В® 1096/LTC1096L/LTC1098/LTC1098L are
    micropower, 8-bit A/D converters that draw only 80ОјA of
    supply current when converting. They automatically power
    down to 1nA typical supply current whenever they are not
    performing conversions. They are packaged in 8-pin SO
    packages and have both 3V (L) and 5V versions. These
    8-bit, switched-capacitor, successive approximation ADCs
    include sample-and-hold. The LTC1096/LTC1096L have a
    single differential analog input. The LTC1098/LTC1098L
    offer a software selectable 2-channel MUX. n 80ОјA Maximum Supply Current

    Richard Markell, Editor
    Introduction
    Over the past several years Linear Technology, the magazine, has come of age. From nothing, the publication has
    come into its own, as has its subscriber list. Many innovative circuits have seen the light of day in the pages of our
    now hallowed publication. This Application Note is meant to consolidate the circuits
    from the first few years of the magazine in one place.
    Circuits herein range from laser diode driver circuits to
    data acquisition systems to a 50W high efficiency switcher
    circuit. Enough said. I’ll stand aside and let the authors
    explain their circuits.

    Micropower 12-Bit ADCs Shrink Board Space – 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
    difficult 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

    The LTC1096 and LTC1098: Micropower, SO-8, 8-Bit ADCs
    Sample at 1kHz on 3µA of Supply Current – Design Note 60
    William Rempfer and Marco Pan
    The LTC В®1096 and LTC1098 are the lowest power,
    most compact, sampling analog-to-digital converters
    in the world. These new 8-bit micropower, sampling
    ADCs typically draw 100ОјA of supply current when
    sampling at 33kHz. Supply current drops linearly as
    the sample rate is reduced as shown in Figure 1. At a
    1kHz sample rate, the supply current is only 3ОјA. The
    ADCs automatically power down when not performing
    conversions, drawing only leakage current. will run off a Panasonic CR1632 3V lithium coin cell
    for п¬Ѓve years.
    The automatic shutdown has great advantages over
    the alternative of high side switching a higher power
    ADC, shown in Figure 3. First, no switching signal or
    hardware is required. Second, power consumption is
