ISL26102 & ISL26104 Analog to Digital Converters

Renesas Electronics ISL26102 and ISL26104 analog to digital converters provide a low-noise programmable gain amplifier along with a 24-bit Delta-Sigma Analog-to-Digital Converter with two-channel (ISL26102) or four-channel (ISL26104) differential, multiplexed inputs. The devices feature conversion rates ranging from 2.5Sps to 4kSps and use a serial interface for communication. The on-chip low-noise programmable-gain amplifier provides gains of 1 to 128, which supports ±19.5mVFS from a 5V reference. The high input impedance allows direct connection of sensors to ensure the specified measurement accuracy without additional circuitry. The Delta-Sigma ADC features a 3rd-order modulator providing up to 21.5-bit noise-free performance (10Sps), with user-selectable word rates. The converter can be operated from an external clock source, an external crystal (typically 4.9152MHz), or the on-chip oscillator. The ISL26102 comes as a TSSOP-24 package and ISL26104 is available as a TSSOP-28 package. The devices have a temperature range of -40°C to +105°C).
