General DescriptionThe MAX1338 14-bit, analog-to-digital converter (ADC)
offers four simultaneously sampled, fully differential input
channels, with independent track-and-hold (T/H) circuitry
for each channel. The input channels are individually
software programmable for input ranges of ±10V, ±5V,
±2.5V, and ±1.25V. The input channels feature fault tol-
erance to ±17V. The internal T/H circuits have a 16ns
aperture delay and 100ps aperture-delay matching.
A 14-bit parallel bus provides the conversion result with
a maximum per-channel output rate of 150ksps
(600ksps for all four channels). The MAX1338 has an
on-board oscillator and 2.5V internal reference. An
external clock and/or reference can also be used.
The MAX1338 operates from a +5V supply for analog
inputs and digital core. The device operates from a +2.7V
to +5.25V supply for the digital I/O lines. The MAX1338
features two power-saving modes: standby mode and
shutdown mode. Standby mode allows rapid wake-up
and reduces quiescent current to 4mA (typ), and shut-
down mode reduces sleep current to less than 10µA (typ).
The MAX1338 is available in an 8mm x 8mm x 0.8mm,
56-pin, thin QFN package. The device operates over
the extended -40°C to +85°C temperature range.

MAX1338
Detailed DescriptionThe MAX1338 simultaneously samples four differential
analog inputs with internal T/H circuits, and sequentially
converts them to a digital code with a 14-bit ADC.
Output data is provided by a 14-bit parallel interface. At
power-up, all channels default to a ±10V input range.
Program different input ranges (±10V, ±5V, ±2.5V, or
±1.25V) using the configuration register. Different input
ranges between ±12V and ±1.0V are realized using an
external reference. All channels offer input protection to
±17V, independent of the selected input range.
The internal clock operates the ADC at 5MHz, or uses
an external conversion clock from 1MHz to 6MHz. EOC
goes low when the result of each conversion is avail-
able, and EOLCgoes low when the last conversion
result is available. Standby and shutdown modes,
selectable through logic-control inputs, save power
between conversions. Figure2 shows a block diagram
of the MAX1338.
