LTC2493IDE: 24-Bit Analog-to-Digital Converter (ADC) with Easy Drive Input Current Offset, DFN-14 

Model: LTC2493IDE 

Package: DFN-14 

Type: Analog-to-Digital Converter (ADC)

The LTC2493IDE is a 4-channel (2 differential channels), 24-bit, No Latency ΔΣ™ incremental accumulator (ADC) with Easy Drive technology and a 2-wire, I2C interface. 

The LTC2493 features a high accuracy temperature sensor and an integrated oscillator. The device can be configured to measure an external signal (from a combination of 4 analogue input channels operating in single-ended or differential mode) or its internal temperature sensor.

LTC2493IDE Product Features: 

Up to 2 differential inputs or 4 single-ended inputs 

Easy Drive™ technology enables rail-to-rail inputs with zero differential input current 

Direct digitisation of high impedance sensors with complete accuracy 

2-wire I2C interface with 9 addresses and a global address for synchronisation 

600nVRMS noise 

Integrated high accuracy Temperature sensors 

GND to VCC input/reference common-mode range 

Programmable 50Hz, 60Hz or simultaneous 50Hz/60Hz suppression modes 

2ppm INL, no missing codes 

1ppm offset and 15ppm full scale error 

2x speed/power-down mode (internal oscillator at 15Hz and 80µA current at 7.5Hz output frequency) 

No delay: digital Filter stabilises in a single cycle (even after selecting a new channel) 

2.7V to 5.5V single-supply operation (0.8mW) 

Internal oscillator 

Slim 4mm x 3mm DFN package

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?
