ADS1201 高动态范围 Δ-Σ 调制器
ADS1201 相关产品
The ADS1201 is a precision, 130dB dynamic range,
delta-sigma (DS) modulator operating from a single
+5V supply. The differential inputs are ideal for direct
connection to transducers or low level signals. With
the appropriate digital filter and modulator rate, the
device can be used to achieve 24-bit analog-to-digital
(A/D) conversion with no missing codes. Effective
resolution of 20 bits can be maintained with a digital
filter bandwidth of 1kHz at a modulator rate of 320kHz.
The ADS1201 is designed for use in high resolution
measurement applications including smart transmitters,
industrial process control, weigh scales, chromatography,
and portable instrumentation. It is available
in a 16-lead SOIC package.
