They have an SPI serial interface, with 16-bit word format. The TPC2160 and TPC2161 are reset to zero code. Digital-To-Analog Sections A simplified DAC diagram is shown below. The 16 bits of the data word drive switches S0 to S15 of a 16-bit voltage mode R-2R ladder network. www.3peakic.com.cn 11 / 18 TPC2160/TPC2161 16 bit High Accuracy DAC Feature Description Output Range The output of the DAC is 𝑉𝑂𝑈𝑇 = (𝑉𝑅𝐸𝐹 × 𝐶𝑜𝑑𝑒)⁄65536 Where Code is the decimal data word loaded to the DAC latch. Power-On Reset The TPC2160 and TPC2161 have power on reset function, to make sure the output is a known state at power-up, and the DAC Registers are zero until new data are loaded. Therefore, after power-up, the output of VOUT is 0 V. Serial Interface The digital interface is a standard 3-wire serial interface compatible with SPI. ̅̅̅̅ turns low, the transmission is started, and the SDI data is shifted in and latched on the edge of SCLK. When CS The data registers are 16-bit, so ̅̅̅̅ CS must go high after 16 SCLKs to transfer a whole data word. In the TPC2160, the input register is latched to DAC immediately after the input register is loaded, so the DAC output is updated at the same time. The TPC2161 has an ̅̅̅̅̅̅̅̅ LDAC pin. After ̅̅̅̅ CS goes high, the DAC register can be updated by bringing ̅̅̅̅̅̅̅̅ LDAC low. be tied low permanently, And ̅̅̅̅̅̅̅̅ LDAC can also in this case, the DAC register is updated immediately after the input register is loaded, and DAC output is updated at the same time. www.3peakic.com.cn 12 / 18 TPC2160/TPC2161 16 bit High Accuracy DAC TPC2160 Unipolar Output Operation DAC Latch Contents MSB LSB Analog Input 1111 1111 1111 1111 VREF × (65,535 / 65,536) 1000 0000 0000 0000 VREF × (32,768 / 65,536) = ½ VREF 0000 0000 0000 0001 VREF× (1 / 65,536) 0000 0000 0000 0000 0V Considering gain error, INL and zero-scale error, the worst-case output voltage may be calculated by following equation: Unipolar Mode Worst-Case Output 𝑉𝑂𝑈𝑇_𝑈 = 𝐷 × (𝑉𝑅𝐸𝐹 + 𝑉𝐺𝐸 ) + 𝑉𝑍𝑆𝐸 + 𝐼𝑁𝐿 216 Where: VOUT_U = Unipolar mode worst-case output D = Code loaded to DAC VREF = Reference voltage VGE = Gain error in volts VZSE = Zero-scale error in volts INL = Integral nonlinearity in volts www.3peakic.com.cn 13 / 18 TPC2160/TPC2161 16 bit High Accuracy DAC TPC2161 Bipolar Output Operation DAC Latch Contents MSB LSB Analog Input 1111 1111 1111 1111 + VREF × (32,767 / 32,768) 1000 0000 0000 0001 + VREF × (1 / 32,768) 1000 0000 0000 0000 0V 0111 1111 1111 1111 − VREF× (1 / 32,768) 0000 0000 0000 0000 − VREF × (32,768 / 32,768) = − VREF Considering non-idealities of external amplifier, the worst-case output voltage may be calculated from the following equation: Bipolar Mode Worst-Case Output 𝑉𝑂𝑈𝑇_𝐵 = [(𝑉𝑂𝑈𝑇_𝑈 + 𝑉𝑂𝑆 )(2 + 𝑅𝐸) − 𝑉𝑅𝐸𝐹 (1 + 𝑅𝐸)] 2 + 𝑅𝐸 1+ 𝐴 Where: VOS = External operational amplifier input offset voltage RE = RFB and RIN resistor matching error A = Operational amplifier open-loop gain www.3peakic.com.cn 14 / 18 TPC2160/TPC2161 16 bit High Accuracy DAC Output Amplifier Selection For bipolar mode, to provide the ±VREF output, a precision amplifier should be used, supplied from a dual power supply. In a single-supply application, selection of a suitable operational amplifier is also important. Input offset, input bias current, rail-to- rail input and output range, -3dB bandwidth and slew rate, are key features for amplifier selection. Power Supply and Reference Bypassing It is recommended that the reference and supply pins are bypassed with a 10 uF tantalum capacitor in parallel with a 0.1 uF ceramic capacitor, for good supply and noise suppression, and then accurate performance, www.3peakic.com.cn 15 / 18 TPC2160/TPC2161 16 bit High Accuracy DAC Tape and Reel Information Order Number Package D1 W1 A0 B0 K0 P0 W0 Pin1 Quadrant TPC2160S1L1A-SO1R-S SOP-8 330.0 17.6 6.4 5.4 2.1 8.0 12.0 Q1 TPC2161S1L1-SO2R SOP-14 330.0 21.6 6.5 9.0 2.1 8.0 16.0 Q1 www.3peakic.com.cn 16 / 18 TPC2160/TPC2161 16 bit High Accuracy DAC Package Outline Dimensions SOP-8 A2 C θ L1 A1 e E D E1 Symbol b Dimensions Dimensions In In Millimeters Inches Min Max Min Max A1 0.100 0.250 0.004 0.010 A2 1.350 1.550 0.053 0.061 b 0.330 0.510 0.013 0.020 C 0.190 0.250 0.007 0.010 D 4.70 5.100 0.188 0.197 E 3.800 4.000 0.150 0.157 E1 5.800 6.300 0.228 0.248 e www.3peakic.com.cn 17 / 18 1.270TYP 0.050TYP L1 0.400 1.270 0.016 0.050 θ 0° 8° 0° 8° TPC2160/TPC2161 16 bit High Accuracy DAC SOP-14 D Dimensions In Millimeters Symbol E1 E e b MIN TYP MAX A 1.35 1.60 1.75 A1 0.10 0.15 0.25 A2 1.25 1.45 1.65 b 0.36 D 8.53 8.63 8.73 E 5.80 6.00 6.20 E1 3.80 3.90 4.00 e L A A2 A1 1.27 BSC 0.45 0.60 L1 1.04 REF L2 0.25 BSC θ L L1 0.49 0° 0.80 8° θ L2 3PEAK and the 3PEAK logo are registered trademarks of 3PEAK INCORPORATED.
