- Typical Application
The 3PA5510 is a monolithic, single supply, 8bit, 20 MSPS analog to digital converter with an on chip sample and hold amplifier. The 3PA5510 uses multi-stage differential pipeline architecture at 20 MSPS data rates and guarantees no missing codes over the full operating temperature range. It operates with a single 5-V supply and typically consumes only 130 mW of power. Also included are parallel outputs with high-impedance mode, and internal reference resistors.
The pipeline architecture reduces power consumption and die size compared to flash converters. The latency of the data output valid is 3.5 clocks.
A single clock input is used to control all internal conversion cycles. The digital output data is presented in straight binary output format.
The 3PA5510 uses the three internal reference resistors to create a standard, 2-V, full-scale conversion range using VDDA. No external connection is required to generate the reference voltage. Differential linearity is 0.5 LSB at 25oC 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 3PA5510 is characterized for operation from –20oC to 75oC.
