Data Sheet

AD7915/AD7916

FEATURES

GENERAL DESCRIPTION

Low power dissipation

AD7915

The AD7915/AD7916 are 16-bit, successive approximation,

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

power supply, VDD. They contain a low power, high speed,

16-bit sampling ADC and a versatile serial interface port. On

the CNV rising edge, the AD7915/AD7916 sample the voltage

difference between the IN+ and IN− pins. e voltages on these

4 mW at 1 MSPS (VDD only)

7 mW at 1 MSPS (total)

AD7916

2 mW at 500 kSPS (VDD only)

3.7 mW at 500 kSPS (total)

pins typically swing in opposite phases between 0 V and V_REF

16-bit resolution with no missing codes

Throughput: 1 MSPS (AD7915)/500 kSPS (AD7916)

INL: 0.4 LSB typical, 1 LSB maximum

SNR: 94 dB at 1 kHz, V_REF= 5 V

SINAD: 93.5 dB at 1 kHz, V_REF= 5 V

THD: −118.5 dB at 1 kHz

Dynamic range: 95.5 dB, V_REF= 5 V

True differential analog input range: V_REF

0 V to V_REFwith V_REFbetween 2.4 V and 5.1 V

No pipeline delay

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

interface

Proprietary serial interface: SPI-/QSPI-/MICROWIRE™-/DSP-

compatible¹

Ability to daisy-chain multiple ADCs

10-lead packages: MSOP and 3 mm × 3 mm LFCSP

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

independent of the supply voltage, VDD. The power consumption

of the AD7915/AD7916 scales linearly with throughput.

The AD7915/AD7916 are serial peripheral interface (SPI)

compatible, which features the ability, using the SDI input, to

daisy-chain several ADCs on a single 3-wire bus. They are

compatible with 1.8 V, 2.5 V, 3 V, and 5 V logic using the

separate VIO supply.

The AD7915/AD7916 are available in a 10-lead MSOP or a

10-lead LFCSP with operation specified from −40°C to +125°C.
