16-BIT, 1.25 MSPS, PSEUDO-BIPOLAR, FULLY DIFFERENTIAL INPUT, MICRO POWER
SAMPLING ANALOG-TO-DIGITAL CONVERTER WITH PARALLEL INTERFACE
• DWDM• Pseudo-Bipolar, Fully Differential Input, -V REF
to V REF • Instrumentation
• High-Speed, High-Resolution, Zero Latency• 16-Bit NMC at 1.25 MSPS
Data Acquisition Systems• ± 2 LSB INL Max, -1/+1.25 LSB DNL
• Transducer Interface• 90 dB SNR, -95 dB THD at 100 kHz Input
• Medical Instruments• Zero Latency
• Communications• Internal 4.096 V Reference
• High-Speed Parallel Interface
• Single 5 V Analog Supply The ADS8406 is a 16-bit, 1.25 MHz A/D converter
• Wide I/O Supply: 2.7 V to 5.25 V with an internal 4.096-V reference. The device in-
cludes a 16-bit capacitor-based SAR A/D converter• Low Power: 155 mW at 1.25 MHz Typ
with inherent sample and hold. The ADS8406 offers a• Pin Compatible With ADS8412/8402
full 16-bit interface and an 8-bit option where data is• 48-Pin TQFP Package
read using two 8-bit read cycles.
The ADS8406 has a pseudo-bipolar, fully differential
input. It is available in a 48-lead TQFP package and
is characterized over the industrial -40 ° C to 85 ° C
temperature range.
