The XRD87L75 is an 8-bit Analog-to-Digital Converter in a small 20 pin SOIC package that operates at 3.3 V. Designed using an advanced CMOS process, this part offers excellent performance, low power consumption and latch-up free operation.
This device uses a two-step flash architecture to maintain low power consumption at high conversion rates. The input circuitry of the XRD87L75 includes an on-chip S/H function and allows the user to digitize analog input signals between GND and VDD. Careful design and chip layout have achieved a low analog input capacitance. This reduces "kickback" and eases the requirements of the buffer/amplifier used to drive the XRD87L75.
The designer can choose the internally generated reference voltages by connecting VRB to VRBS and VRT to VRTS, or provide external reference voltages to the VRB and VRT pins. The internal reference generates 0.4V at VRB and 1.72V at VRT. Providing external reference voltages allows easy interface to any input signal range between GND and VDD. This also allows the system to adjust these voltages to cancel zero scale and full scale errors, or to change the input range as needed.
The device operates from a single +3.3 V supply ±10%. Power consumption is 20mW at Fs = 10MHz.
Specified for operation over the commercial/industrial (-40 to +85°C) temperature range, the XRD87L75 is available in Plastic dual-in-line (PDIP), Surface Mount (SOIC) and Shrunk small outline (SSOP) packages.
