Signal Processing

Low-power 14-bit ADC

Linear Technology's LTC2351-14, a 1.5 Msps low-power ADC, has six simultaneous differential sampling inputs. Operating from a single 3.3 V supply, power dissipation is typically 16.5 mW. The device features six individual sample-and-hold amplifiers, a multiplexer, and a single ADC. When the device is not converting, power dissipation can be further reduced to 4.5 mW in Nap mode with the internal 2.5 V reference remaining active, and to 12 µW in sleep mode, with all internal circuitry powered down. The internal 2.5 V reference can be overdriven with an external reference, up to the analog supply voltage.

The LTC2351-14 uses three input-select lines to configure the number of differential inputs converted. Thus, higher speeds are possible, from one differential input at 1.5 Msps to six differential inputs at 250 ksps. The six conversion results are delivered sequentially to a high-speed DSP serial port via a three-wire interface. This ADC also features a separate digital output power supply pin and a bipolar/unipolar input line to select ±1.25 V bipolar or 0 V to 2.5 V unipolar input ranges.

For lower-resolution applications, the company is introducing the pin and code-compatible 12-bit LTC2351-12 ADC. Both the LTC2351-14 and LTC2351-12 are available in the commercial and industrial temperature ranges. Pricing begins at $9.45 each for the LTC2351-14 and $6.95 each for the LTC2351-12, in 1000-piece quantities.
