12-Bit, 1MSPS SAR ADCs
ISL267450
The ISL267450 is a 12-bit, 1MSPS sampling SAR-type ADC with
a differential input span of 2*VREF volts. The ISL267450 features
excellent linearity over supply and temperature variations and is
drop-in compatible with the AD7450. The device can operate
from a supply voltage of either 5V or 3V and maintain
measurement accuracy with input signals up to the supply rails.
The serial digital interface is SPI compatible and is easily
interfaced to popular FPGAs and microcontrollers. Power
dissipation is 9.0mW at a sampling rate of 1MSPS, and just 5µW
between conversions utilizing Auto Power-Down mode (with a 3V
supply).
The ISL267450 is available in 8 Ld SOIC or MSOP packages, and
are specified for operation over the Industrial temperature range
(–40°C to +85°C).
Features
• Drop-in Compatible with AD7450
• Differential Input
• Simple SPI-compatible Serial Digital Interface
• Guaranteed No Missing Codes
• 1MHz Sampling Rate
• 3V or 5V Operation
• Low Operating Current
- 1.25mA at 833kSPS with 3V Supplies
- 1.7mA at 1MSPS with 5V Supplies
• Power-down Current between Conversions: 1µA
• Excellent Differential Non-Linearity
• Low THD: -83dB (typ)
• Pb-Free (RoHS Compliant)
• Available in SOIC and MSOP Packages

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil
Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL267450. For more information on MSL please see techbrief TB363.
