• Four Individually Configurable GPIOs for easy connection with microprocessors and DSP. TSSOP package devices. One GPIO for QFN devices The input signal is sampled with the falling edge of CS. It uses SCLK for conversion, serial data output,PCA9544AGQNR Texas Instruments(TI) IC MUX 4CH I2C/SMBUS 20-BGA
• Typical Power Dissipation: 14.5 mW (+VA = 5V, and reading serial data in. The devices allow auto +VBD = 3V) at 1 MSPS sequencing of preselected channels or manual
• Power-Down Current (1 mA) selection of a channel for the next conversion cycle.
• Input Bandwidth (47 MHz at 3dB) There are two software selectable input ranges (0V -
• 38-,30-Pin TSSOP and 32-,24-Pin QFN 2.5V and 0V - 5V), four individually configurable Packages GPIOs ( in case of TSSOP package devices), and two programmable alarm thresholds per channel. APPLICATIONS These features make the devices suitable for most data acquisition applications.PCA9544AGQNR Texas Instruments(TI) IC MUX 4CH I2C/SMBUS 20-BGA
