MAX1165BCUI
Low-Power, 16-Bit Analog-to-Digital Converters with Parallel Interface
General Description
The MAX1165/MAX1166 16-bit, low-power, successive-
approximation analog-to-digital converters (ADCs) fea-
ture automatic power-down, factory-trimmed internal
clock, and a 16-bit wide (MAX1165) or byte wide
(MAX1166) parallel interface. The devices operate from
a single +4.75V to +5.25V analog supply and a +2.7V
to +5.25V digital supply.
The MAX1165/MAX1166 use an internal 4.096V refer-
ence or an external reference. The MAX1165/MAX1166
consume only 1.8mA at a sampling rate of 165ksps with
external reference and 2.7mA with internal reference.
AutoShutdown™ reduces supply current to 0.1mA at
10ksps.
The MAX1165/MAX1166 are ideal for high-perfor-
mance, battery-powered, data-acquisition applications.
Excellent dynamic performance and low power con-
sumption in a small package make the MAX1165/
MAX1166 ideal for circuits with demanding power con-
sumption and space requirements.
The 16-bit wide MAX1165 is available in a 28-pin
TSSOP package and the byte wide MAX1166 is avail-
able in a 20-pin TSSOP package. Both devices are
available in either the 0°C to +70°C commercial, or the
-40°C to +85°C extended temperature range.

Detailed Description
Converter Operation
The MAX1165/MAX1166 use a successive-approxima-
tion (SAR) conversion technique with an inherent track-
and-hold (T/H) stage to convert an analog input into a
16-bit digital output. Parallel outputs provide a high-
speed interface to most microprocessors (µPs). The
Functional Diagramshows a simplified internal archi-
tecture of the MAX1165/MAX1166. Figure 3 shows a
typical application circuit for the MAX1166.
Analog Input
The equivalent input circuit is shown in Figure 4. A
switched capacitor digital-to-analog converter (DAC)
provides an inherent T/H function. The single-ended
input is connected between AIN and AGND.
Input Bandwidth
The ADC’s input-tracking circuitry has a 4MHz small-
signal bandwidth, so it is possible to digitize high-
speed transient events and measure periodic signals
with bandwidths exceeding the ADC’s sampling rate by
using undersampling techniques. To avoid aliasing of
unwanted high-frequency signals into the frequency
band of interest, use anti-alias filtering.
Analog Input Protection
Internal protection diodes, which clamp the analog
input to AVDDand/or AGND, allow the input to swing
from AGND - 0.3V to AVDD+ 0.3V, without damaging
the device.
If the analog input exceeds 300mV beyond the sup-
plies, limit the input current to 10mA.
