This device offers a unique combination of excellent dc accuracy and outstanding ac performance. The high-order, chopper-stabilized modulator achieves very low drift with low in-band noise. The integrated decimation filter suppresses modulator out-of-band noise. In addition to al lowlatency filter, the ADS127L01 provi...
