Compact outline for
speedy sampling ADCs
Three new families of simultaneous-sampling 14bit ADCs offer choices of 0 to 5, +/-5 and +/-10V analogue inputs
The 0 to 5V versions (MAX1316, MAX1317 and MAX1318) provide +/-6V overvoltage fault protection, whereas the MAX1324 and MAX1325 +/-5 and +/-10V devices (the MAX1320, MAX1321, MAX1322 and MAX1326, respectively) provide +/-16.5V overvoltage fault protection. These new ADC families have excellent dynamic performance (spurious-free dynamic range of 93dBc, signal to noise and distortion ratio of 76dB) and DC accuracy (+/-2LSB integral nonlinearity and +/-1LSB dynamic nonlinearity).

The MAX2120 is ideal for DVB-S and free-to-air applications in which low cost and ease of use are key requirements
Packaged in 7 x 7mm 48-pin TQFPs, these ICs are the smallest ADCs in their class.
Compared with competing four-channel simultaneously-sampling ADCs and even Maxim's previous four-channel simultaneously-sampling versions, the MAX1316, MAX1320 and MAX1324 sample up to eight channels simultaneously.
All the new ADCs offer bipolar inputs without negative supply requirements, and give a 2.5x improvement in sampling rate and reducing the footprint by 2.3x.
The devices are available in eight-channel (MAX1316, MAX1320 and MAX1324), four-channel (MAX1317, MAX1321 and MAX1325), and two-channel (MAX1318, MAX1322 and MAX1326) versions.
These ADCs integrate a high-speed 15MHz parallel interface, internal 2.5V reference, and an internal or external conversion clock.
The MAX1316-MAX1326 family converts two channels in 2us or eight channels in 3.8us, and has an eight-channel throughput of 263Ksample/s per channel.
These devices accept bipolar or unipolar inputs while operating from a 5V analogue and 2.7 to 5.25V digital supply.
A first-in/first-out buffer reduces interface overhead and allows conversion results to be read at the end of the conversion sequence or between conversions.
The devices operate over the extended (-40 to +85C) temperature range.
Prices start at $10.75 (1000-up, FOB USA).
