The MAX1307/MAX1311/MAX1315 12-bit, analog-to-digital
converters (ADCs) feature a 1075ksps sampling rate, a
20MHz input bandwidth, and three analog input ranges.
The MAX1307 provides a 0 to +5V input range, with ±6V
fault-tolerant inputs. The MAX1311 provides a ±5V input
range with ±16.5V fault-tolerant inputs. The MAX1315 provides
a ±10V input range with ±16.5V fault-tolerant inputs.
The MAX1307/MAX1311/MAX1315 include an on-chip
2.5V reference. These devices also accept an external
+2V to +3V reference.
All devices operate from a +4.75 to +5.25V analog supply,
and a +2.7V to +5.25V digital supply. The devices
consume 36mA total supply current when fully operational.
A 0.62µA shutdown mode is available to save
power during idle periods.
A 20MHz, 12-bit, parallel data bus provides the conversion
results. An internal 15MHz oscillator, or an externally
applied clock, drives conversions.
Each device is available in a 48-pin 7mm x 7mm
TQFP package and operates over the extended
(-40°C to +85°C) temperature range.
