AD7607:  200 kSPS, 8-Channel, Simultaneous Sampling, Bipolar 14-Bit ADC

The AD76071 is an eight channel simultaneously sampled 14-bit ADC. The AD7607 is capable of achieving a sampling rate of 200 ksps per channel. The input signals are sampled simultaneously thus preserving the relative phase information of the signals on the input channels. The part operates from a 5V supply and can accommodate ± 10V and ±5V true bipolar input signals. The part contains ...More

AD7607:  200 kSPS, 8-Channel, Simultaneous Sampling, Bipolar 14-Bit ADC

Product Description

The AD76071 is an eight channel simultaneously sampled 14-bit ADC. The AD7607 is capable of achieving a sampling rate of 200 ksps per channel. The input signals are sampled simultaneously thus preserving the relative phase information of the signals on the input channels. The part operates from a 5V supply and can accommodate ± 10V and ±5V true bipolar input signals. The part contains on-chip LDOs, reference and reference buffer, track and hold circuitry, supply conditioning circuitry, on-chip conversion clock, oversampling capability and high speed parallel and serial interfaces.

The AD7607 features throughput rates up to 200 kSPS per channel. The part contains low noise, high input impedance signal scaling amplifiers that can handle input frequencies in the region of 5 to10 Khz. The AD7607 features a front-end anti-alias filter with attenuation of approximately 40dB while sampling at 200kSPS. The conversion process and data acquisition are controlled using CONVST signals and an internal oscillator. Two CONVST pins allow the simultaneous sampling of all eight analog inputs or two groups of four analog input channels. The AD7607 provides over sampling capability. Over sampling is optional to achieve improved noise performance and reduced output code spread for lower throughput rates.
