ADC12010
12-Bit, 10 MSPS, 160 mW A/D Converter with Internal
Sample-and-Hold
General Description
The ADC12010 is a monolithic CMOS analog-to-digital con-
verter capable of converting analog input signals into 12-bit
digital words at 10 Megasamples per second (MSPS), mini-
mum. This converter uses a differential, pipeline architecture
with digital error correction and an on-chip sample-and-hold
circuit to minimize die size and power consumption while
providing excellent dynamic performance. Operating on a
single 5V power supply, this device consumes just 160 mW
at 10 MSPS, including the reference current. The Power
Down feature reduces power consumption to 25 mW.
The differential inputs provide a full scale input swing equal
to 2VREF with the possibility of a single-ended input. Full use
of the differential input is recommended for optimum perfor-
mance. For ease of use, the buffered, high impedance,
single-ended reference input is converted on-chip to a differ-
ential reference for use by the processing circuitry. Output
data format is 12-bit offset binary.
This device is available in the 32-lead LQFP package and
will operate over the industrial temperature range of −40˚C to
+85˚C.

Description
Non-Inverting analog signal Input. With a 2.0V reference
voltage, the ground-referenced input signal level is 2.0 VP-P
centered on VCM.
Inverting analog signal Input. With a 2.0V reference voltage
the ground-referenced input signal level is 2.0 VP-P centered
on VCM. This pin may be connected to VCM for single-ended
operation, but a differential input signal is required for best
performance.
1 VREF
Reference input. This pin should be bypassed to AGND with
a 0.1 µF monolithic capacitor. VREF is 2.0V nominal and
should be between 1.0V to 2.4V.

These pins are high impedance reference bypass pins.
Connect a 0.1 µF capacitor from each of these pins to AGND.
DO NOT LOAD these pins.
Digital clock input. The range of frequencies for this input is
100 kHz to 15 MHz (typical) with guaranteed performance at
10 MHz. The input is sampled on the rising edge of this input.
OE is the output enable pin that, when low, enables the
TRI-STATE® data output pins. When this pin is high, the
outputs are in a high impedance state.
PD is the Power Down input pin. When high, this input puts
the converter into the power down mode. When this pin is
low, the converter is in the active mode.
