The MAX1307/MAX1311/MAX1315 12-bit, analog-to-digi-
tal 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 ±±V
fault-tolerant inputs. The MAX1311 provides a ±5V input
range with ±1±.5V fault-tolerant inputs. The MAX1315 pro-
vides a ±10V input range with ±1±.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 sup-
ply, and a +2.7V to +5.25V digital supply. The devices
consume 3±mA total supply current when fully opera-
tional. A 0.±2µA shutdown mode is available to save
power during idle periods.

A 20MHz, 12-bit, parallel data bus provides the conver-
sion results. An internal 15MHz oscillator, or an externally
applied clock, drives conversions.
