S9408

SUMMIT MICROELECTRONICS, Inc. S9408 Serial Input, Quad 8-Bit Nonvolatile DACPOT™ FEATURES Four 8-Bit DACS – Differential Non-linearity - ±0.5LSB max – Integral Non-Linearity - ±1LSB max Each DAC has Independent Reference Inputs – Output Buffer Amplifiers Swing Rail-to-Rail – Ground to VDD Reference Input Range Each DAC’s Digital Input Data Maintained in Nonvolatile EEPROM Power-On Reset Reloads Registers with Nonvolatile Data www.DataSheet4U.com DAC values, OVERVIEW The S9408 DACPOT™ is a serial input, voltage output, quad 8-bit digital to analog converter. The S9408 operates from a single +2.7V to +5.5V supply. Internal precision buffers swing rail-to-rail and the reference input range includes both ground and the positive supply. The S9408 integrates four 8-bit DACs and their associated circuits which include an enhanced unity-gain operational amplifier output, an 8-bit data latch, an 8-bit nonvolatile register, and an industry-standard serial interface for reading and writing data to the DACs’ data latches and registers. The DACs are independently programmable and each has its own electrically isolated Vreference inputs. Simple Serial Interface for Reading and Writing SPI™ and QSPI™ compatible. Fully operational from 2.7V to 5.5V Low Power: <1mW @ 2.7V FUNCTIONAL BLOCK DIAGRAM Memory Control 8-Bit E2PROM DAC SECTION 0 2 VREFH0 VDD 3 Serial Data In 8-Bit Data Register 8-Bit DAC AMP 18 VOUT0 RDY/BSY# 4 Programming Memory Controller 11 Serial D...
