MAX6079 Low-Noise Precision Ceramic Voltage Reference General Description Benefits and Features The MAX6079 offers a very low noise and low-drift 8-pin Ceramic Package Reduces System Board voltage reference in a small 8-pin Ceramic package. The Space device provides a 1/f noise voltage of only 4.8V at an P-P Hermetically Sealed Ceramic Package Offers Stable output voltage of 2.5V, with a temperature drift of 6ppm/C Results vs. Time, Humidity and Temperature (max). The device consumes 160A of supply current Stable Performance Over Temperature and Time and can sink and source up to 10mA of load current. The Improves System Accuracy low-drift and low-noise specifications enable enhanced High 0.08% Initial Accuracy system accuracy, making these devices ideal for high- Low 1.5ppm/C (typ), 6ppm/C (max) Temperature precision industrial applications. The MAX6079 offers a Drift noise filter option for wideband applications. Low 4.8V Noise (0.1Hz to 10Hz) at 2.5V P-P The MAX6079 is available in an 8-pin Ceramic package Low 200mV Dropout Voltage and is specified over the extended industrial temperature High 85dB Ripple Rejection range of -40C to +125C. Low 160A Supply Current Reduces Power Applications Consumption High-Accuracy Industrial and Process Control Filter Option Lowers High-Frequency Noise Precision Instrumentation Ordering Information and Selector Guide appears at end of High-Resolution ADCs and DACs data sheet.
