FEATURES  
DESCRIPTIO  
2-Channel Differential Input with Automatic  
The LTC®2436-1 is a 2-channel differential input mi-  
cropower 16-bit No Latency ∆ΣTM analog-to-digital con-  
verter with an integrated oscillator. It provides 0.5LSB  
INL and 800nV RMS noise independent of VREF. The two  
differential channels convert alternately with a channel  
identification included in the conversion result. It uses  
delta-sigma technology and provides single conversion  
settling of the digital filter. Through a single pin, the  
LTC2436-1 can be configured for better than 87dB input  
differential mode rejection at 50Hz and 60Hz ±2%, or it  
can be driven by an external oscillator for a user defined  
rejection frequency. The internal oscillator requires no  
external frequency setting components.  
Channel Selection (Ping-Pong)  
Low Supply Current: 200µA, 4µA in Autosleep  
Differential Input and Differential Reference with  
GND to VCC Common Mode Range  
0.12LSB INL, No Missing Codes  
0.16LSB Full-Scale Error and 0.006LSB Offset  
800nV RMS Noise, Independent of VREF  
No Latency: Digital Filter Settles in a Single Cycle and  
Each Channel Conversion is Accurate  
Internal Oscillator—No External Components  
Required  
87dB Min, 50Hz and 60Hz Notch Filter  
Narrow SSOP-16 Package  
The converter accepts any external differential reference  
voltage from 0.1V to VCC for flexible ratiometric and  
remote sensing measurement configurations. The full-  
scale differential input range is from 0.5 • VREF to 0.5 •  
VREF. The reference common mode voltage, VREFCM, and  
the input common mode voltage, VINCM, may be indepen-  
dently set anywhere between GND and VCC. The DC  
common mode input rejection is better than 140dB.  
Single Supply 2.7V to 5.5V Operation  
Pin Compatible with the 24-Bit LTC2412
