LTC2295 Dual 14-Bit, 10Msps Low Power 3V ADC FEATURES DESCRIPTIO Integrated Dual 14-Bit ADCs The LTC 2295 is a 14-bit 10Msps, low power dual 3V Sample Rate: 10Msps A/D converter designed for digitizing high frequency, wide Single 3V Supply (2.7V to 3.4V) dynamic range signals. The LTC2295 is perfect for Low Power: 120mW demanding imaging and communications applications 74.4dB SNR with AC performance that includes 74.4dB SNR and 90dB 90dB SFDR SFDR for signals well beyond the Nyquist frequency. 110dB Channel Isolation DC specs include 1.2LSB INL (typ), 0.5LSB DNL (typ) Multiplexed or Separate Data Bus and no missing codes over temperature. The transition Flexible Input: 1V to 2V Range P-P P-P noise is a low 1LSB . RMS 575MHz Full Power Bandwidth S/H Clock Duty Cycle Stabilizer A single 3V supply allows low power operation. A separate Shutdown and Nap Modes output supply allows the outputs to drive 0.5V to 3.6V Pin Compatible Family logic. An optional multiplexer allows both channels to 105Msps: LTC2282 (12-Bit), LTC2284 (14-Bit) share a digital output bus. 80Msps: LTC2294 (12-Bit), LTC2299 (14-Bit) A single-ended CLK input controls converter operation. An 65Msps: LTC2293 (12-Bit), LTC2298 (14-Bit) optional clock duty cycle stabilizer allows high perfor- 40Msps: LTC2292 (12-Bit), LTC2297 (14-Bit) mance at full speed for a wide range of clock duty cycles. 25Msps: LTC2291 (12-Bit), LTC2296 (14-Bit) , LTC and LT are registered trademarks of Linear Technology Corporation. 10Msps: LTC2290 (12-Bit), LTC2295 (14-Bit) All other trademarks are the property of their respective owners. 64-Pin (9mm 9mm) QFN Package U APPLICATIO S Wireless and Wired Broadband Communication Imaging Systems Spectral Analysis Portable Instrumentation TYPICAL APPLICATIO Typical INL, 2V Range OV DD 2.0 + 14-BIT INPUT ANALOG D13A PIPELINED 1.5 OUTPUT INPUT A S/H ADC CORE DRIVERS D0A 1.0 OGND 0.5 0 CLOCK/DUTY CYCLE CLK A CONTROL 0.5 MUX 1.0 CLOCK/DUTY CYCLE CLK B CONTROL 1.5 OV 2.0 DD 8192 16384 0 4096 12288 D13B CODE + OUTPUT 14-BIT ANALOG INPUT DRIVERS 2295 G02 PIPELINED D0B INPUT B S/H ADC CORE OGND 2295 TA01 2295fa 1 INL ERROR (LSB) U ULTC2295 UUW ABSOLUTE AXI U RATI GS PACKAGE/ORDER I FOR ATIO OV = V (Notes 1, 2) DD DD TOP VIEW Supply Voltage (V ) ................................................. 4V DD Digital Output Ground Voltage (OGND) ....... 0.3V to 1V Analog Input Voltage (Note 3) ..... 0.3V to (V + 0.3V) DD + A 1 48 DA7 INA Digital Input Voltage .................... 0.3V to (V + 0.3V) DD A 2 47 DA6 INA REFHA 3 46 DA5 Digital Output Voltage ................ 0.3V to (OV + 0.3V) DD REFHA 4 45 DA4 REFLA 5 44 DA3 Power Dissipation............................................ 1500mW REFLA 6 43 DA2 V 7 42 DA1 Operating Temperature Range DD CLKA 8 41 DA0 65 LTC2295C ............................................... 0C to 70C CLKB 9 40 OFB V 10 39 DB13 DD LTC2295I.............................................40C to 85C REFLB 11 38 DB12 REFLB 12 37 DB11 Storage Temperature Range ..................65C to 125C REFHB 13 36 DB10 REFHB 14 35 DB9 A 15 34 DB8 INB + A 16 33 DB7 INB UP PACKAGE 64-LEAD (9mm 9mm) PLASTIC QFN T = 125C, = 20C/W JMAX JA EXPOSED PAD (PIN 65) IS GND AND MUST BE SOLDERED TO PCB ORDER PART QFN PART* NUMBER MARKING LTC2295CUP LTC2295UP LTC2295IUP Order Options Tape and Reel: Add TR Lead Free: Add PBF Lead Free Tape and Reel: Add TRPBF Lead Free Part Marking:
