Product Summary

The TLC548 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 TLC548 useonly 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 TLC548 is 2.048 MHz.

Parametrics

The absolute maximum ratings of TLC548CD 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: 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 TLC548CD 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–TLC548:up to 45 500; (6)On-Chip Software-Controllable Sample-and-Hold Function; (7)Total Unadjusted Error:±0.5 LSB MaxD 4-MHz Typical Internal System Clock; (8)Wide Supply Range:3 V to 6 V; (9)Low Power Consumption:15 mW Max; (10)Ideal for Cost-Effective, High-Performance Applications including Battery-Operated Portable Instrumentation; (11)Pinout and Control Signals Compatible; (12)CMOS Technology
