产品信息

描述The TLC1550x and TLC1551 are data acquisition analog-to-digital converters (ADCs) using a 10-bit, switched-capacitor, successive-approximation network. A high-speed, 3-state parallel port directly interfaces to a digital signal processor (DSP) or microprocessor (µP) system data bus. D0 through D9 are the digital output terminals with D0 being the least significant bit (LSB). Separate power terminals for the analog and digital portions minimize noise pickup in the supply leads. Additionally, the digital power is divided into two parts to separate the lower current logic from the higher current bus drivers. An external clock can be applied to CLKIN to override the internal system clock if desired. The TLC1550I and TLC1551I are characterized for operation from –40°C to 85°C. The TLC1550M is characterized over the full military range of –55°C to 125°C.特性Power Dissipation...40 mW Max Advanced LinEPIC™ Single-Poly Process Provides Close Capacitor Matching for Better Accuracy Fast Parallel Processing for DSP and µP Interface Either External or Internal Clock Can Be Used Conversion Time...6 µs Total Unadjusted Error...±1 LSB Max CMOS TechnologyAdvanced LinEPIC is a trademark of Texas Instruments.
