The LTC2499CUHF#PBF is a 16-channel 24-bit delta-sigma A/D Converter with easy drive input current cancellation and I2C interface. The patented sampling scheme eliminates dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current. This allows large external source impedances and input signals with rail-to-rail input range to be directly digitized while maintaining exceptional DC accuracy. The LTC2499 includes a high accuracy, temperature sensor and an integrated oscillator. This device can be configured to measure an external signal (from combinations of 16 analogue input channels operating in single- ended or differential modes) or its internal temperature sensor. The integrated temperature sensor offers 1/30th°C resolution and 2°C absolute accuracy. Any combination of single-ended or differential inputs can be selected and the first conversion, after a new channel is selected, is valid.

• Up to eight differential or 16 single-ended inputs
• Easy Drive? technology enables rail-to-rail inputs with zero differential input current
• Directly digitizes high impedance sensors with full accuracy
• 2-wire I2C interface with 27 addresses plus one global address for synchronization
• 600nVRMS Noise
• Integrated high accuracy temperature sensor
• GND to VCC Input/reference common mode range
• Programmable 50, 60Hz or simultaneous 50/60Hz rejection mode
• 2ppm INL, no missing codes
• 1ppm offset and 15ppm full-scale error

• 2x Speed/reduced power mode (15Hz using internal oscillator and 80μA at 7.5Hz output)
• No latency, digital filter settles in a single cycle even after a new channel is selected
• Internal oscillator
