TLC5510 ADC IC Chip

TLC5510(8-BIT HIGH-SPEED ANALOG-TO-DIGITAL CONVERTERS)

Introduction

The TLC5510 and TLC5510A are CMOS, 8-bit, 20 MSPS analog-to-digital converters (ADCs) that utilize a semiflash architecture. The TLC5510 and TLC5510A operate with a single 5V supply and typically consume only 130 mW of power.Included is an internal sample -and-hold circuit, parallel outputs with high-impedance mode, and internal reference resistors.

The semiflash architecture reduces power consumption and die size compared to flash converters. By implementing the conversion in a 2-step process, the number of comparators is significantly reduced. The latency of the data output valid is 2.5 clocks.

The TL C5510 uses the three internal reference resistors to create a standard,2V,full- scale conversion range using VDDA.

This option only requires external jumpers for implementation and eliminates the need for external reference resistors. The TLC5510A utilizes only the center internal resistor section with an externally applied 4-V reference, allowing for the use of a 4-V input signal.Differential linearity is 0.5 LSB at 25°C and a maximum of 0.75 LSB over the full operating temperature range. Typical dynamic specifications include a differential gain of 1% and differential phase of 0.7 degrees.

The TLC5510 and TLC5510A are characterized for operation from -20°C to 75°C.
