FEATURES  
DESCRIPTIO  
The LTC®1863/LTC1867 are pin-compatible, 8-channel  
12-/16-bit A/D converters with serial I/O, and an internal  
reference. The ADCs typically draw only 1.3mA from a  
single 5V supply.  
Sample Rate: 200ksps  
16-Bit No Missing Codes and ±2LSB Max INL  
8-Channel Multiplexer with:  
Single Ended or Differential Inputs and  
Unipolar or Bipolar Conversion Modes  
The 8-channel input multiplexer can be configured for  
either single-ended or differential inputs and unipolar  
or bipolar conversions (or combinations thereof). The  
automatic nap and sleep modes benefit power sensitive  
applications.  
SPI/MICROWIRETM Serial I/O  
Signal-to-Noise Ratio: 89dB  
Single 5V Operation  
On-Chip or External Reference  
Low Power: 1.3mA at 200ksps, 0.76mA at 100ksps  
The LTC1867’s DC performance is outstanding with a  
±2LSB INL specification and no missing codes over tem-  
perature. The signal-to-noise ratio (SNR) for the LTC1867  
is typically 89dB, with the internal reference.

Automatic Nap Mode Between Conversions  
16-Pin Narrow SSOP Package  
U
APPLICATIO S  
Housed in a compact, narrow 16-pin SSOP package, the  
LTC1863/LTC1867 can be used in space-sensitive as well  
as low-power applications.
