    U DESCRIPTIO FEATURES









    ■ The LTC®1415 is a 700ns, 1.25Msps, 12-bit sampling
    A/D converter that draws only 55mW from a single 5V
    supply. This easy-to-use device includes a high dynamic
    range sample-and-hold, precision reference and a trimmed
    internal clock. Two power shutdown modes provide flexibility for low power systems. 1.25Msps Sample Rate

    1.25Msps, 12-Bit ADC Conserves Power and
    Signal Integrity on a Single 5V Supply – Design Note 146
    Kevin R. Hoskins
    INTRODUCTION Complete ADC with Reference and Wideband S/H
    The LTC1415 includes a 10ppm/°C 2.5V reference that
    is suitable for use as a system reference. This internal
    reference sets the LTC1415’s full-scale input range from
    0V to 4.096V. The circuit in Figure 2 trims the full-scale
    (gain) error without placing additional circuitry in the
    signal path. The new LTC®1415 expands LTC’s family of high speed,
    low power 12-bit ADCs. Operating on a single 5V supply,
    it is optimized for applications such as ADSL, HDSL,
    modems, direct down-conversion, CCD imaging,
    DSP-based vibration analysis, waveform digitizers and
    multiplexed systems. The LTC1415’s block diagram is
    shown in Figure 1. The LTC1415’s fully differential S/H has a typical 20MHz
    input bandwidth and very good CMRR of 60dB or better over a DC to 10MHz bandwidth. AC specifications
    are measured with single-ended (–A IN grounded)
    signal drive. Offsetting –AIN above ground eases the
    drive requirements of rail-to-rail op amps that drive the
    LTC1415’s input. Single 5V Supply, High Speed, Lowest Power
    The new LTC1415 has lower power dissipation and better performance and features than other 12-bit ADCs
    currently on the market. It samples at 1.25Msps and ...
