ADS1202  
SBAS275B – DECEMBER 2002 – REVISED JULY 2004  
Motor Control Current Shunt  
1-Bit, 10MHz, 2nd-Order, Delta-Sigma Modulator  
FEATURES  
16-BIT RESOLUTION  
DESCRIPTION  
The ADS1202 is a precision, 80dB dynamic range, delta-  
sigma (∆Σ) modulator operating from a single +5V supply.  
The differential inputs are ideal for direct connections to  
transducers or low-level signals. With the appropriate digital  
filter and modulator rate, the device can be used to achieve  
16-bit Analog-to-Digital (A/D) conversion with no missing  
codes. Effective resolution of 12 bits can be maintained with  
a digital filter bandwidth of 10kHz at a modulator rate of  
10MHz. The ADS1202 is designed for use in medium reso-  
lution measurement applications including current measure-  
ments, smart transmitters, industrial process control, weigh  
scales, chromatography, and portable instrumentation. It is  
available in a TSSOP-8 package.
