The MAX1307 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 MAX1307 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.
