MAX1324ECM+ 14-Bit, Simultaneous-Sampling ADCs with ±10V, ±5V, and 0 to +5V Analog Input Ranges LQFP-48 spot stock

Product Descriptions

The MAX1316–MAX1318/MAX1320–MAX1322/MAX1324– MAX1326 14-bit, analog-to-digital converters (ADCs) offer two,  four,  or  eight  independent  input  channels. Independent track/hold (T/H) circuitry provides simultaneo us  sampling  for  each  channel.  The  MAX1316/ MAX1317/MAX1318 have a 0 to +5V input range with±6 .0V fault-tolerant inputs. The MAX1320/MAX1321/ MAX1322 have a ±5V input range with ±16 .5V fault-tolerant inputs. The MAX1324/MAX1325/MAX1326 have a±10V input range with ±16 .5V fault-tolerant inputs. These ADCs convert two channels in 2µs, and up to eight channels in 3.8µs, and have an 8-channel throughput of250ksps per channel. Other features include a 10MHz T/H input bandwidth, internal clock, internal (+2 .5V) or external (+2 .0V to  +3 .0V)  reference, and  powersaving modes.

A 16.6MHz, 14-bit, bidirectional, parallel interface provides the conversion 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 50mA total supply current. 

These devices come in a 48-pin LQFP package and operate over the extended -40°C to +85°C temperature range.
