LTC1650 Low Glitch 16-Bit Voltage Output DAC FEATURES DESCRIPTIO n 16-Bit Monotonic Over Temperature The LTC 1650 is a deglitched rail-to-rail voltage output n Low Glitch Impulse: 2nV-s 16-bit digital-to-analog converter (DAC) available in a n Low Noise: 30nV/ Hz 16-pin narrow SO package. It has 16-bit monotonicity n Buffered Rail-to-Rail Voltage Output over temperature and includes a rail-to-rail output buffer n Low Power: 50mW from 5V Supplies amplifier and an easy to use three-wire cascadable serial n Unipolar or Bipolar Output (0V to V or V ) interface. The LTC1650 operates with dual 5V supplies. REF REF n 4-Quadrant Multiplying Capability With REFLO = 0V and REFHI = V , the output will swing REF n Asynchronous Clear to User-Defined Voltage from 0V to V in unipolar mode or V in bipolar REF REF n Power-On Reset mode. TM n Three-Wire SPI and MICROWIRE Compatible The LTC1650 has excellent accuracy over its full operating Serial Interface n temperature range along with very low power dissipation Schmitt Trigger On CLK Input Allows Direct of 50mW with dual 5V supplies. This, along with the Optocoupler Interface n small outline package, makes it the most flexible high 16-Pin Narrow SO Package resolution digital-to-analog converter available today. U The LTC1650 has a fast settling time of 4m s to 16 bits and APPLICATIO S a low midscale glitch of under 2nV-s. This makes the n Industrial Process Control LTC1650 ideal for waveform generation or other applica- n Precision Industrial Equipment tions where output dynamic performance is important. n Waveform Generation , LTC and LT are registered trademarks of Linear Technology Corporation. n Automatic Test Equipment MICROWIRE is a trademark of National Semiconductor Corporation. n High Resolution Offset and Gain Adjustment TYPICAL APPLICATIO 5V 5V 4.096V RSTOUT DV AV DD REFHI DD Differential Nonlinearity 3 11 10 15 vs Input Code CS/LD 8 1.0 CLK 7 POWER-ON RESET 0.8 CLR 9 SUPPLY SENSE D 5 IN 0.6 2 V RST 0.4 0.2 0 16-BIT + DAC 0.2 1 V OUT 0.4 0.6 0.8 D 6 OUT 1.0 16 UNI/BIP 0 16384 32768 49152 65535 CODE 4 12,13 14 1650 TA02 1650 TA01 DGND REFLO AV SS 5V 1 16-BIT SHIFT REGISTER 16-BIT DAC REGISTER DNL ERROR (LSB) U ULTC1650 UUW ABSOLUTE AXI U RATI GS PACKAGE/ORDER I FOR ATIO (Note 1) TOP VIEW ORDER PART AV , DV to DGND .............................. 0.5V to 7.5V DD DD NUMBER 1 V 16 UNI/BIP OUT TTL Input Voltage .................................... 0.5V to 7.5V 2 V 15 AV RST DD LTC1650ACN V , V ................................ 0.5V to (AV + 0.5V) 3 OUT RST DD DV 14 AV DD SS LTC1650AIN AV .........................................................0.5V to 7.5V 4 DGND 13 REFLO S SS LTC1650ACS 5 Operating Temperature Range D 12 REFLO F IN LTC1650AIS 6 D 11 REFHI LTC1650C .............................................. 0 C to 70 C OUT LTC1650CN 7 CLK 10 RSTOUT LTC1650I............................................ 40 C to 85 C LTC1650IN 8 CS/LD 9 CLR Maximum Junction Temperature ......................... 125 C LTC1650CS Storage Temperature Range ................. 65 C to 150 C N PACKAGE S PACKAGE LTC1650IS 16-LEAD PDIP 16-LEAD PLASTIC SO Lead Temperature (Soldering, 10 sec)................. 300 C T = 125 C, q = 85 C/ W (N) JMAX JA T = 125 C, q = 130 C/ W (S) JMAX JA Consult LTC Marketing for parts specified with wider operating temperature ranges.
