MAX1327ECM+T

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P18P19-P20
General Description
The MAX1319/MAX1323/MAX1327 are single-channel,
14-bit, 526ksps analog-to-digital converters (ADCs) with
±2 LSB INL and ±1 LSB DNL with no missing codes. The
MAX1323 has a ±5V input range with ±16.5V fault-toler-
ant inputs. The MAX1327 has a ±10V input range with
±16.5V fault-tolerant inputs and the MAX1319 has a 0 to
+5V input range with ±6.0V fault-tolerant inputs. Other
features include a 10MHz track/hold (T/H) input band-
width, internal clock, internal (+2.5V) or external (+2.0V
to +3.0V) reference, and shutdown mode.
A 16.6MHz, 14-bit, parallel interface provides the con-
version results and accepts digital configuration inputs.
These devices operate from a +4.75V to +5.25V analog
supply and a separate +2.7V to +5.25V digital supply,
and consume less than 35mA total supply current. For
multichannel applications, refer to the MAX1316–
MAX1318/MAX1320–MAX1322/MAX1324–MAX1326
data sheet.
These devices come in a 48-pin TQFP package and
operate over the extended -40°C to +85°C tempera-
ture range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
