DESCRIPTIONThe ADS1605 and ADS1606 are high-speed, high-pre-
cision, 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 per-
formance 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 adjust-
able first-in first-out buffer (FIFO) for the output data.
The input signal is measured against a voltage refer-
ence that can be generated on-chip or supplied exter-
nally. The digital output data are 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 equip-
ment, data acquisition, and medical imaging.
