FEATURES

DESCRIPTION

NOTE: Some device/package combinations are

obsolete and are described and shown here for

reference only. See our web site for product

availability.

•

Serial I/O (MICROWIRE, SPI and QSPI

Compatible)

•

Power Down Mode

Programmable Acquisition Time

The ADC12130, ADC12132 and ADC12138 are 12-

bit plus sign successive approximation Analog-to-

Digital converters with serial I/O and configurable

input multiplexer. The ADC12132 and ADC12138

have a 2 and an 8 channel multiplexer, respectively.

The differential multiplexer outputs and ADC inputs

are available on the MUXOUT1, MUXOUT2, A/DIN1

and A/DIN2 pins. The ADC12130 has a two channel

multiplexer with the multiplexer outputs and ADC

inputs internally connected. The ADC12130 family is

tested and specified with a 5 MHz clock. On request,

these ADCs go through a self calibration process that

adjusts linearity, zero and full-scale errors to typically

less than ±1 LSB each.

Variable Digital Output Word Length and

Format

•

No Zero or Full Scale Adjustment Required

0V to 5V Analog Input Range with Single 5V

Power Supply

APPLICATIONS

•

Pen-Based Computers

Digitizers

Global Positioning Systems

KEY SPECIFICATIONS

The analog inputs can be configured to operate in

various combinations of single-ended, differential, or

pseudo-differential modes. A fully differential unipolar

analog input range (0V to +5V) can be

accommodated with a single +5V supply. In the

differential modes, valid outputs are obtained even

when the negative inputs are greater than the positive

because of the 12-bit plus sign output data format.

•

Resolution 12-bit plus sign

12-Bit plus sign conversion time 8.8 μs (max)

12-Bit plus sign throughput time 14 μs (max)

Integral Linearity Error ±2 LSB (max)

Single Supply 3.3V or 5V ±10%

Power Consumption

The serial I/O is configured to comply with NSC

MICROWIRE. For voltage references, see the

LM4040, LM4050 or LM4041.

–

+3.3V 15 mW (max)

+3.3V power down 40 μW (typ)

+5V 33 mW (max)

+5V power down 100 μW (typ)
