DESCRIPTION  
The ADS8887 is an 18-bit, 100-kSPS, true-differential  
input, analog-to-digital converter (ADC). The device  
operates with a 2.5-V to 5-V external reference,  
offering a wide selection of signal ranges without  
additional input signal scaling. The reference voltage  
setting is independent of, and can exceed, the analog  
supply voltage (AVDD).  
SPI™-Compatible Serial Interface with  
Daisy-Chain Option  
Excellent AC and DC Performance:  
SNR: 100 dB, THD: –115 dB  
INL: ±1.5 LSB (typ), ±3.0 LSB (max)  
DNL: +1.5 and –1 LSB (max), 18-Bit NMC  
The device offers an SPI-compatible serial interface  
that also supports daisy-chain operation for  
cascading multiple devices.  
Wide Operating Range:  
AVDD: 2.7 V to 3.6 V  
DVDD: 1.65 V to 3.6 V  
(Independent of AVDD)  
The device supports unipolar, true-differential analog  
input signals with a differential input swing of –VREF to  
+VREF. This true-differential analog input structure  
allows for a common-mode voltage of any value in  
the range of 0 V to +VREF (when both inputs are  
within the operating input range of –0.1 V to VREF  
+ 0.1 V).  
REF: 2.5 V to 5 V (Independent of AVDD)  
Operating Temperature: –40°C to +85°C  
Low-Power Dissipation:  
0.7 mW at 100 kSPS  
70 µW at 10 kSPS  
Device operation is optimized for very low-power  
operation. Power consumption directly scales with  
speed. This feature makes the ADS8887 excellent for  
lower-speed applications.  
Power-Down Current (AVDD): 50 nA  
Full-Scale Step Settling to 18 Bits: 1200 ns
