500ksps, Low-Power,
Serial 12-/10-/8-Bit ADCs
General Description
The MAX11661−MAX11666 are 12-/10-/8-bit, compact,
low-power, successive approximation analog-to-digital
converters (ADCs). These high-performance ADCs include
a high-dynamic range sample-and-hold and a high-speed
serial interface. These ADCs accept a full-scale input from
0V to the power supply or to the reference voltage.
The MAX11662/MAX11664/MAX11666 feature dual, sin-
gle-ended analog inputs connected to the ADC core
using a 2:1 MUX. The devices also include a separate
supply input for data interface and a dedicated input
for reference voltage. In contrast, the single-channel
devices generate the reference voltage internally from
the power supply.
These ADCs operate from a 2.2V to 3.6V supply and
consume only 3.3mW. The devices include full power-
down mode and fast wake-up for optimal power man-
agement and a high-speed 3-wire serial interface. The
3-wire serial interface directly connects to SPIK, QSPIK,
and MICROWIREK devices without external logic.
Excellent dynamic performance, low voltage, low power,
ease of use, and small package size make these con-
verters ideal for portable battery-powered data-acquisi-
tion applications, and for other applications that demand
low-power consumption and minimal space.
These ADCs are available in a 10-pin FMAX® package,
and a 6-pin SOT23 package. These devices operate
over the -40NC to +125NC temperature range.
