A proprietary input multiplexer and combination buffer amplifier reduces the input drive requirements, resulting in lower cost and reduced board space. Specified measurement accuracy is maintained with input signals up to VDD. Members of the ISL26320/21/22/23/24/25/29 family of Low-Power ADCs offer pinout intercompatibility, differing only in the analog inputs, to support quick replication of proven layouts across multiple design platforms. The serial digital interface is SPI compatible and is easily interfaced to popular FPGAs and microcontrollers. Power consumption is limited to 15mW at a sampling rate of 250kSPS, and an operating current of just 8μA typical between conversions, when configured for Auto Powerdown mode. The ISL26320/21/22/23/24/25/29 feature up to 5kV Human Body Model ESD survivability and are available in the popular SOIC and TSSOP packages. Performance is specified for operation over the full industrial temperature range (-40°C to +125°C). Features • Pin-compatible Family Allows Easy Design Upgrades • Excellent Differential Non-Linearity (0.7LSB max) • Low THD: -86dB (typ) • Simple SPI-compatible Serial Digital Interface • Low 3mA Operating Current • Power-down Current between Conversions 8μA (typ) • +5.25V to +2.7V Supply • Excellent ESD Survivability: 5kV HBM, 350V MM, 2kV CDM Applications • Industrial Process Control • Energy Measurement • Multichannel Data Acquisition Systems • Pressure Sensors • Flow Controllers FIGURE 1.
