D AC9377 Series D ata Converter Line Complete Buffered 16-Bit D AC FEATURES • • • • • • • True 16-bit (0.0008% ) linearity µP compatible Complete 24-pin package Low power — 450mW Low cost Binary or BCD code DESCRIPTION The DA C9377-16 is a complete, voltage output 16-bit D/A converter with true 16-bit linearity. Complete with storage registers, internal reference and output amplifier, the DA C9377-16 provides the user with exceptional performance and self-contained operation. The input storage register is composed of 16 parallel latches — a system compatible with 16-bit data bus interfaces. A single proprietary monolithic chip contains switches, storage registers and other electronics for high resolution and low linearity error. TTL and CM OS compatibility combined with low power dissipation in a ceramic 24-pin DIP makes the DA C9377-16 unsurpassed in a high resolution data conversion device. True 16-Bit Linearity — 16-bit (±0.0008% ) linearity in a 24-pin DIP is unequaled. No other microcircuit converter does better. A dditional versions with 15and 14-bit linearity are also available. Low Pow er — CM OS proprietary monolithic devices in a unique circuit configuration yield the lowest power dissipation (450 mW typ.) of any complete 16bit converter available. Complete — No external components are required for 16-bit conversion. FUNCTIONAL DIAGRAM LA TCH CONTROL DIGITA L INPUTS (M SB) BIT 1 2 8 7 Input Storage Registers — Designed in one 16-bit segment, the input storage register provides data storage when latched, but is “ transparent” when unlatched. The latch control is level triggered for either static or dynamic operation. Reliability — A proven performer, the DA C9377-16 is packaged in a 24-pin ceramic DIP for the utmost in reliability. Combined with our proprietary monolithic device and automatic wirebonding, we‘ve made the DA C9377-16 the most reliable device to date. Reliability is further enhanced by batch-processed, precision laser-trimmed resistor networks fabricated in our own facility. A dvanced designs, proven processes and continuous monitoring during all production operations by our quality control organization are combined with rigorous A QL screening to provide the most dependable, low cost D/A converter possible. 3 6 4 5 5 4 6 3 16 7 1 8 9 10 24 23 22 11 12 13 14 21 20 19 18 (LSB) 15 16 17 16 DA C9377 INPUT REGISTER 5k* – + 16-BIT M DA C – + 5k 5k V OLTA GE REF * TOLERA NCE ±30% 14 12 15 13 GA IN A DJUST +15V – 15V GND 13 BIPOLA R 13 SUM M ING JUNCTION 165Cedar Hill Street,Marlborough,MA01752 Tel:508.485.6350 Fax: 508.485.5168 www.SpectrumMicrowave.com 10 V OUT DAC9377 SPECIFICATIO N S (Typical @+25ºC unipolar operation and nominal power supply, no load) M ODEL DA C9377-16-6 TY PE Latched Inputs DA C9377-16-5 DA C9377-16-4 DA C9377-4D DIGITA L INPUT Resolution Unipolar Coding Bipolar Coding Logic Compatibility1 Input Leakage Current Latch Control W idth Data Set-up Time 2 Data Hold Time 3 16-Bits Binary Offset Binary TTL.

Digital input voltage must not exceed supply voltage or go below –0.5V ; 2. Time. data must be stable before latch control goes to “ 0” . 3. Time, data must be stable after latch control goes to “ 0” . 4. See A PPLICA TIONS INFORM A TION for calibration procedure. 5. See A PPLICA TIONS NOTES. 6. Integral Linearity, for this product, is measured as the arithmetic mean value of the magnitudes of the greatest positive deviation and the greatest negative deviation from the theoretical value for any given input combination. 7. Differential Linearity is the deviation of an output step from the theoretical value of 1 LSB for any two adjacent digital input codes. 1.310 (33.274) MAX 24 0.165 (4.191) MAX 13 Pin Connections Unipolar Output: Ground pin 11 (No Connection for BCD) Bipolar OutPut: Connect pin 11 to pin 9 (Binary Only) PIN DESIGNA TIONS 0.80 (20.321) MAX 0.600 ± 0.010 (15.24 ± 0.25) PIN FUNCTION Binary BCD 2– 8 (100) 2– 7 (200) PIN 2– 6 2– 5 2– 4 (400) 22 (800) 21 (1000) 20 (2000) 19 7 2– 3 2– 2 (4000) 8 2– 1 (8000) 1 1 12 PIN (1) INDEX 0.100 ±0.005 TY P (2.54 ±0.13) 0.010 + 0.002 – 0.001 (0.25 + 0.005 – 0.003) 0.025 + 0.010 (0.64 + 0.25) 0.205 (5.21) M IN DIM ENSIONS inches (mm) 0.018 ±0.002 (0.46 ±0.05) 2 3 4 5 6 24 FUNCTION Binary BCD 2– 9 (80) 2 – 10 2 – 11 (40) 2 – 12 2 – 13 (10) (4) 18 2 – 14 2 – 15 17 2 – 16 (1) 23 (20) (8) (2) 9 SUM M ING JUNCTION 16 LA TCH CONTROL 10 OUT 15 -15V 11 BIPOLA R 14 GA IN A DJUST 12 +15V 13 GND N/C Note on BCD pin 11 must have no connection Consult factory for application information.
