描述The ADS1209 is a two-channel, high-performance, delta-sigma () modulator with an 86dB dynamic range, operating from a single +5V supply. The differential inputs are ideal for direct connection to signal sources in an industrial environment. 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 accuracy of 14 bits can be obtained with a digital filter bandwidth of 20kHz at a modulator rate of 10MHz. The ADS1209 is designed for use in high-resolution measurement applications including current measurements, industrial process control, and resolvers. It is available in a TSSOP-24 package and is specified for operation over the ambient temperature range of –40°C to +105°C.特性16-Bit Resolution 13-Bit Linearity±2.3V SpecifiedInput Voltage Range Internal Reference Voltage: 2% Gain Error: 0.5% Two Independent Delta-Sigma Modulators Two Input Reference Buffers On-Chip Oscillator Selectable Internal or External Clock Specified Temperature Range: –40°C to +105°C TSSOP-24 Package APPLICATIONSMotor Control Current MeasurementResolver Industrial Process Control Instrumentation All trademarks are the property of their respective owners.
