16-Bit Lower Power

PulSAR ADCs in MSOP/LFCSP (QFN)

Data Sheet

AD7988-1/AD7988-5

FEATURES

GENERAL DESCRIPTION

Low power dissipation

AD7988-5: 3.5 mW @ 500 kSPS

AD7988-1: 700 µW @ 100 kSPS

16-bit resolution with no missing codes

Throughput: 100 kSPS/500 kSPS options

INL: 0.6 LSB typical, 1.25 LSB maximum

SINAD: 91.5 dB @ 10 kHz

The AD7988-1/AD7988-5 are 16-bit, successive approximation,

analog-to-digital converters (ADC) that operate from a single

power supply, VDD. The AD7988-1 offers a 100 kSPS throughput,

and the AD7988-5 offers a 500 kSPS throughput. They are low

power, 16-bit sampling ADCs with a versatile serial interface

port. On the CNV rising edge, they sample an analog input,

IN+, between 0 V to V_REFwith respect to a ground sense, IN−.

The reference voltage, REF, is applied externally and can be set

independent of the supply voltage, VDD.

THD: −114 dB @ 10 kHz

Pseudo differential analog input range

0 V to V_REFwith V_REFfrom 2.5 V to 5.5 V

Any input range and easy to drive with the ADA4841-1

No pipeline delay

Single-supply 2.5 V operation with 1.8 V/2.5 V/3 V/5 V

logic interface

The SPI-compatible serial interface also features the ability to

daisy-chain several ADCs on a single 3-wire bus using the SDI

input. It is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic using

the separate supply, VIO.

The AD7988-1/AD7988-5 generics are housed in a 10-lead

MSOP or a 10-lead LFCSP (QFN) with operation specified

from −40°C to +125°C.

SPI-/QSPI-/MICROWIRE™-/DSP-compatible serial interface

Daisy-chain multiple ADCs

10-lead MSOP and 10-lead, 3 mm × 3 mm LFCSP (QFN),

same space as SOT-23
