DESCRIPTION
The ADS1605 and ADS1606 are high-speed, high-precision,
delta-sigma analog-to-digital converters (ADCs) with 16-bit
resolution. The data rate is 5 mega-samples per second
(MSPS), the bandwidth (3dB) is 2.45MHz, and passband
ripple is less than
±
0.0025dB (to 2.2MHz). Both devices offer
the same outstanding performance at these speeds with a
signal-to-noise ratio up to 88dB, total harmonic distortion
down to 99dB, and a spurious-free dynamic range up to
101dB. For even higher-speed operation, the data rate can
be doubled to 10MSPS in 2X mode. The ADS1606 includes
an adjustable first-in first-out buffer (FIFO) for the output data.
The input signal is measured against a voltage reference that
can be generated on-chip or supplied externally. The digital
output data is provided over a simple parallel interface that
easily connects to digital signal processors (DSPs). An
out-of-range monitor reports when the input range has been
exceeded. The ADS1605/6 operate from a +5V analog
supply (AVDD) and +3V digital supply (DVDD). The digital
I/O supply (IOVDD) operates from +2.7 to +5.25V, enabling
the digital interface to support a range of logic families. The
analog power dissipation is set by an external resistor and
can be reduced when operating at slower speeds. A power
down mode, activated by a digital I/O pin, shuts down all
circuitry. The ADS1605/6 are offered in a TQFP-64 package
using TI PowerPAD
technology.
The ADS1605 and ADS1606, along with their 18-bit
counterparts, the ADS1625 and ADS1626, are well suited
for the demanding measurement requirements of scientific
instrumentation, automated test equipment, data acquisi-
tion, and medical imaging.
