Description

The ADS1610 is a high-speed, high-precision, delta-sigma () analog-to-digital converter (ADC) with 16-bit resolution operating from a 5V analog and a 3V digital supply. Featuring an advanced multi-stage analog modulator combined with an on-chip digital decimation filter, the ADS1610 achieves 86 dBFS signal-to-noise ratio (SNR) in a 5MHz signal bandwidth; while the total harmonic distortion is -94dB.

The ADS1610 topology provides key system-level design advantages with respect to anti-alias filtering and clock jitter. The design of the user's front-end anti-alias filter is simplified since the on-chip digital filter greatly attenuates out-of-band signals. The ADS1610s filter has a brick wall response with a very flat passband (±0.0002dB of ripple) followed immediately by a very wide stop band (5MHz to 55MHz). Clock jitter becomes especially critical when digitizing high frequency, large-amplitude signals. The ADS1610 significantly reduces clock jitter sensitivity by an effective averaging of clock jitter as a result of oversampling the input signal.

Output data is supplied over a parallel interface and easily connects to TMS320 digital signal processors (DSPs). The power dissipation can be adjusted with an external resistor, allowing for reduction at lower operating speeds.

With its outstanding high-speed performance, the ADS1610 is well-suited for demanding applications in data acquisition, scientific instruments, test and measurement equipment, and communications. The ADS1610 is offered in a TQFP64 package and is specified from -40°C to 85°C.
