ADC121S101/ADC101S101/ADC081S101 1MSPS, 12-/10-/8-Bit A/D Converters in SOT-23 & LLP
January 2005
ADC121S101/ADC101S101/ADC081S101
1MSPS, 12-/10-/8-Bit A/D Converters in SOT-23 & LLP
General Description
The ADC121S101, ADC101S101, and ADC081S101 are low
power, monolithic CMOS 12-, 10- and 8-bit analog-to-digital
converters that operate at 1 MSPS. Each device is based on
a successive approximation register architecture with inter-
nal track-and-hold. The serial interface is compatible with
several standards, such as SPI
鈩?/div>
, QSPI
鈩?/div>
, MICROWIRE
鈩?/div>
,
and many common DSP serial interfaces.
The ADC121S101/101S101/081S101 uses the supply volt-
age as a reference. This enables the devices to operate with
a full-scale input range of 0 to V
DD
. The conversion rate is
determined from the serial clock (SCLK) speed. These con-
verters offer a shutdown mode, which can be used to trade
throughput for power consumption. The ADC121S101/
101S101/081S101 are operated with a single supply that
can range from +2.7V to +5.25V. Normal power consumption
during continuous conversion, using a +3V or +5V supply, is
2 mW or 10 mW, respectively. The power down feature,
which is enabled by a chip select (CS) pin, reduces the
power consumption to under 5 碌W using a +5V supply. All
three converters are available in a 6-lead SOT-23 package,
which provides an extremely small footprint for applications
where space is a critical consideration. The ADC081S101 is
also available in a 6-lead LLP package. These products are
designed for operation over the industrial temperature range
of 鈭?0藲C to +85藲C, with some parameters specified to
+125藲C for the ADC121S101.
