The LTC2324-14 is a low noise, high speed quad 14-bit + sign successive approximation register (SAR) ADC with differential inputs and wide input common mode range. Operating from a single 3.3V or 5V supply, the LTC2324-14 has an 8VP-P differential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC232414 achieves ±1LSB INL typical, no missing codes at 14 bits and 81dB SNR.

The LTC2324-14 has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference. The LTC2324-14 also has a high speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 2Msps per channel throughput with no latency makes the LTC2324-14 ideally suited for a wide variety of high speed applications. The LTC2324-14 dissipates only 40mW per channel and offers nap and sleep modes to reduce the power consumption to 26μW for further power savings during inactive periods.

Product Detail

Demonstration circuit 2395A features the LTC2325/LTC2324/LTC2320 family. With up to 5Msps, these differential, multiple channel, 16-bit, serial, high speed successive approximation register (SAR) ADCs are available in a 52-lead QFN package. Each ADC has an internal 20ppm/°C maximum drift reference and an SPI-compatible serial interface that supports CMOS and LVDS logic. Note the demo board is configured for CMOS operation by default; see the note under JP8 for LVDS operation. The datasheet refers to the LTC2325, but applies to all members of the family, the only difference being the number of channels, the sample rate and/or the number of bits. The DC2395A demonstrates the DC and AC performance of the LTC2325 in conjunction with the DC890 PScope data collection board. Alternatively, by connecting the DC2395A into a customer application, the performance of the LTC2325 can be evaluated directly in that circuit.
