Price Comparison for MAX1496EAI+
Series Information for MAX1496EAI+ - Maxim Integrated


The MAX1447/MAX1496/MAX1498 low-power, 3.5- and 4.5-digit, analog-to-digital converters (ADCs) with inte- grated light-emitting diode (LED) drivers operate from a single 2.7V to 5.25V power supply. They include an internal reference, a high-accuracy on-chip oscillator, and a multiplexed LED display driver. An internal charge pump generates the negative supply needed to power the integrated input buffers for single-supply operation. The ADC is configurable for either a ±2V or ±200mV input range and it outputs its conversion results to an LED. The MAX1496 is a 3.5-digit (±1999 count) device and the MAX1447/MAX1498 are 4.5-digit (±19,999 count) devices. The MAX1447/MAX1496/MAX1498 do not require exter- nal precision integrating capacitors, autozero capaci- tors, crystal oscillators, charge pumps, or other circuitry required with dual-slope ADCs (commonly used in panel meter circuits). These devices also feature on-chip buffers for the dif- ferential signal and reference input, allowing direct interface with high-impedance signal sources. In addi- tion, they use continuous internal offset-calibration and offer >100dB rejection of 50Hz and 60Hz line noise. Other features include data hold and peak detection and overrange/underrange detection. The MAX1447 features on-demand enhanced offset calibration for improved offset performance. The MAX1447/MAX1498 are available in a 32-pin, 7mm ✕ 7mm TQFP package and the MAX1496 is available in 28-pin SSOP and 28-pin PDIP packages. All devices in this family operate over the -40°C to +85°C extended temperature range.
