MAXIM INTRODUCES FIRST PRECISION CHIP-SCALE VOLTAGE REFERENCE
SUNNYVALE, CA-November 29, 2001-Maxim Integrated Products introduces the MAX6023, the industry’s first precision voltage reference in an ultra-chip-scale package (UCSP™). This new package is the size of the silicon die with bumps on the bond pads. It measures 1mm long, 1.5mm wide, 0.3mm high, and solders directly to the PC board. The UCSP is five times smaller than the SOT23 plastic surface-mount package.
Unlike traditional two-terminal shunt references, this three-terminal series mode reference does not require an external resistor. Furthermore, the MAX6023 is internally compensated and does not require an external compensation capacitor. Therefore, with its UCSP packaging and elimination of external resistors and capacitors that would normally be larger than the voltage reference itself, the MAX6023 is ideal for applications that have extreme space constraints.
In this tiny UCSP IC is an impressively accurate voltage reference that guarantees an ultra-low 30ppm/°C temperature coefficient with an initial accuracy of 0.2%. The MAX6023 is guaranteed to use less than 35mA supply current, operate from a minimum of 2.5V, and use single-supply voltages up to 12.6V. For output voltages 2.5V and higher, the minimum supply
voltage can be as low as 200mV higher than the output voltage.
The MAX6023 is available in seven factory-preset output voltages: 1.25V, 2.048V, 2.5V, 3V, 4.096V, 4.5V, and 5V. It is shipped in tape-and-reel format to simplify handling. Prices for the MAX6023 in the 5-bump UCSP start at $1.50 (1000-up, FOB USA).
