GENERAL DESCRIPT ION
T he AD7667 is a 16-bit, 1 MSPS, charge redistribution SAR,
analog-to-digital converter that operates from a single 5 V
power supply. T he part contains a high-speed 16-bit sampling
ADC, an internal conversion clock, internal reference, error
correction circuits, and both serial and parallel system inter-
face ports.
It features a very high sampling rate mode (Warp) and, for
asynchronous conversion rate applications, a fast mode
(Normal) and, for low power applications, a reduced power
mode (Impulse) where the power is scaled with the through-
put.
It is fabricated using Analog Devices’ high-performance, 0.6 micron
CMOS process, with correspondingly low cost and is available in a
48-lead LQFP and a tiny 48-lead LFCSP with operation speci-
fied from –40°C to +85°C.
PRODUCT HIGHLIGHT S
1. Fast T hroughput
T he AD7667 is a 1 MSPS, charge redistribution, 16-bit
SAR ADC with internal error correction circuitry.
2. Internal Reference
T he AD7667 has an internal reference and allows for an
external reference to be used.
3. Superior INL
T he AD7667 has a maximum integral nonlinearity of 2.5
LSB with no missing 16-bit code.
4. Single-Supply Operation
T he AD7667 operates from a single 5 V supply and dissipates
a typical of 112 mW. In impulse mode, its power dissi-
pation decreases with the throughput. It consumes 7 μW
maximum when in power-down.
5. Serial or Parallel Interface
Versatile parallel or 2-wire serial interface arrangement
compatible with both 3 V or 5 V logic.
