Texas Instruments (TI) expanded its data converter portfolio today with a new family of small, pin-compatible analog-to-digital converters (ADCs) that provide a best-in-class power-to-performance ratio.
The ADC3k family includes 12- and 14-bit options in speed grades of up to 160 MSPS with 2 or 4 channels and with LVDS or JESD204B interfaces. The devices support the industrial ambient temperature range of -40C to 85C for use in industrial applications, such as motor control, medical imaging, and portable test and measurement, as well as defense and communications applications, such as software defined radio and MIMO communications.
Features:
－ Best-in-class power consumption and power-to-performance ratio: At the fastest sampling rate of 160 MSPS, the devices use only 200 mW/ch, 80 mW/ch less than similar devices, and provide a 30 percent better power-to-performance ratio. Power scales to 44 mW/ch at 25 MSPS.
－ Large, pin-compatible family: Extensive pin-compatible family scales to meet multi-platform system needs for various sampling rates and channel counts.
－ Smallest size reduces board space: 4-channel, 160-MSPS devices are half the size of existing devices.
－ Simplifies board routing: JESD204B variants are compliant with subclass 0, 1, and 2 at up to 3.2 Gbps. They support one lane per ADC output up to 160 MSPS, and one lane per two ADCs for up to 80 MSPS.
－ Unique performance features: Optional dither and chopper functions can improve spurious free dynamic range (SFDR) and remove 1/f noise, which allows designers to optimize device performance to meet system needs.
