LTC2442CG#PBF

LTC®2442 is an ultra-high precision, variable speed, 24bit DS™ ADC with an integrated amplifier. The amplifier can be configured as a buffer for easy input drive of high-impedance sensors. 1 part-per-million (ppm) linearity is achievable when the amplifier is configured in unity gain. External resistors can be used to set a gain for increased resolution of low-level input signals. The positive and negative amplifier supply pins may be tied directly to VCC (4.5V to 5.5V) and GND or biased above VCC and below GND for rail-to-rail input signals. Typical applications include auto ranging 6-digit DVMs, high speed multiplexing, weight scales, direct temperature measurement and high speed data acquisition.

• 1ppm linearity with no missing codes
• Integrated amplifier for direct sensor digitization
• 2 differential or 4 single-ended input channels
• Up to 8KHz output rate (external fo) and up to 4KHz multiplexing rate (external fo)
• Guaranteed modulator stability and lock-up immunity for any input and reference conditions
• Differential input and differential reference with GND to VCC common mode range
• No latency mode, each conversion is accurate even after a new channel is selected
• Internal oscillator, no external components
• 36 lead SSOP package
• Operating temperature range from 0°C to 70°C
