Products Detail

These ADCs include an internal reference, a high-accuracy on-chip oscillator, and a triplexed LCD driver. They are configurable for ±2V or ±200mV input range and output conversion results to an LCD. The MAX1491 is a 3.5-digit device, while MAX1493/MAX1495 are 4.5-digit devices. They do not require external precision components and feature on-chip buffers for differential signal and reference inputs. They offer continuous internal offset calibration and >100dB rejection of 50Hz and 60Hz line noise.
