MAX1447, MAX1496, MAX1498 3.5- And 4.5-Digit, Single-Chip ADCs With LED Drivers

The MAX1447 MAX1496 MAX1498 low-power, 3.5- and 4.5-digit, Analog-to-digital converters (ADCs) with integrated 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 external precision integrating capacitors, autozero capacitors, 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 differential signal and reference input, allowing direct Interface with high-impedance signal sources. In addition, 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 x 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 -40C to +85C extended temperature range.
