Product Summary
The TLC549 are CMOS analog-to-digital converter (ADC) integrated circuits built around an 8-bit switched-capacitor successive-approximation ADC. These devices are designed for serial interface with amicroprocessor or peripheral through a 3-state data output and an analog input. The TLC549 use only the input/output clock (I/O CLOCK) input along with the chip select (CS) input for data control. The maximum I/O CLOCK input frequency of the TLC549 is specified up to 1.1 MHz.
Parametrics
The absolute maximum ratings of TLC549CDG4 are (1)Supply voltage, VCC (see Note 1):6.5 V; (2)Input voltage range at any input:-0.3 V to VCC + 0.3 V; (3)Output voltage range:-0.3 V to VCC + 0.3 V; (4)Peak input current range (any input):±10 mA; (5)Peak total input current range (all inputs):±30 mA; (6)Operating free-air temperature range, TA (see Note 2): TLC548C, TLC549C: 0°C to 70°C; (7)Storage temperature range, Tstg:-65°C to 150°C; (8)Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds:260°C
Features
The features of TLC549CDG4 can be summarized as (1)Microprocessor Peripheral or Standalone Operation; (2)8-Bit Resolution A/D Converter; (3)Differential Reference Input Voltages; (4)Conversion Time:17 μs Max; (5)Total Access and Conversion Cycles Per Second: TLC549 up to 40 000; (6)On-Chip Software-Controllable Sample-and-Hold Function; (7)Total Unadjusted Error:±0.5 LSB Max; (8)4-MHz Typical Internal System Clock; (9)Wide Supply Range: 3 V to 6 V; (10)Low Power Consumption:15 mW Max; (11)Ideal for Cost-Effective, High-Performance Applications including Battery-Operated Portable Instrumentation; (12)Pinout and Control Signals Compatible; (13)CMOS Technology
