DESCRIPTION
High Speed, 16-Bit, 333ksps
Sampling A/D Converter
with Shutdown
The LTC1604 is a 333ksps, 16-bit sampling A/D con-
verter that draws only 220mW from ±5V supplies. This
high performance device includes a high dynamic range
sample-and-hold, a precision reference and a high speed
parallel output. Two digitally selectable power shutdown
modes provide power savings for low power systems.
The LTC1604’s full-scale input range is ±2.5V. Outstand-
ing AC performance includes 90dB S/(N+D) and –100dB
THD at a sample rate of 333ksps.
The unique differential input sample-and-hold can acquire
single-ended or differential input signals up to its 15MHz
bandwidth. The 68dB common mode rejection allows
users to eliminate ground loops and common mode noise
by measuring signals differentially from the source.
The ADC has μP compatible,16-bit parallel output port.
There is no pipeline delay in conversion results. A separate
convert start input and a data ready signal (BUSY) ease
connections to FlFOs, DSPs and microprocessors.
