2
40-kHz Min Sampling Rate  
Very Low Power: 25 mW  
±3.33-V, ±5-V, ±10-V, 4-V, and 10-V Input  
Ranges  
89.9-dB SINAD with 10-kHz Input  
±1.5 LSB Max INL  
±1 LSB Max DNL, 16-Bit NMC  
DESCRIPTION  
±5-mV BPZ, ±0.4 PPM/°C BPZ Drift  
87-dB Min SINAD, 96-dB Min SFDR  
Uses Internal or External 2.5-V Reference  
No External Calibration Resistors Required  
Single 5-V Analog Supply  
The ADS8513 is a complete low-power, single 5-V  
supply, 16-bit sampling analog-to-digital (A/D)  
converter.  
It  
contains  
a
complete  
16-bit  
capacitor-based, successive approximation register  
(SAR) A/D converter with sample and hold, clock,  
reference, and serial data interface. The converter  
can be configured for a variety of input ranges  
including ±10 V, ±5 V, 0 V to 10 V, and 0.5 V to  
4.5 V. A high-impedance, 0.3-V to 2.8-V input is also  
available with input impedance greater than 10 M.  
For most input ranges, the input voltage can swing to  
25 V or –25 V without damage to the converter.  
40-mW Max Power Dissipation  
50-μW Max Power-Down Mode  
20-Mhz Compatible SPI  
Global CONV and 3-Stated Bus for Multi-Chip  
Simultaneous S/H Operation  
Pin-Compatible with ADS7813 and 12-Bit  
ADS7812/8512  
An SPI-compatible serial interface allows data to be  
synchronized to an internal or external clock. The  
ADS8513 is specified at 40-kHz sampling rate over  
the industrial –40°C to 85°C temperature range.
